Sororin is a protein that in humans is encoded by the CDCA5 gene. [5] [6] [7]

Contents

Function

Sororin is required for stable binding of cohesin to chromatin and for sister chromatid cohesion in interphase. [8]

Clinical significance

Transactivation of Sororin and its phosphorylation at Ser209 by ERK play an important role in lung cancer proliferation. [9]

<span class="mw-page-title-main">Spindle apparatus</span> Feature of biological cell structure

In cell biology, the spindle apparatus is the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle during mitosis, a process that produces genetically identical daughter cells, or the meiotic spindle during meiosis, a process that produces gametes with half the number of chromosomes of the parent cell.

<span class="mw-page-title-main">Spindle checkpoint</span> Cell cycle checkpoint

The spindle checkpoint, also known as the metaphase-to-anaphase transition, the spindle assembly checkpoint (SAC), the metaphase checkpoint, or the mitotic checkpoint, is a cell cycle checkpoint during metaphase of mitosis or meiosis that prevents the separation of the duplicated chromosomes (anaphase) until each chromosome is properly attached to the spindle. To achieve proper segregation, the two kinetochores on the sister chromatids must be attached to opposite spindle poles. Only this pattern of attachment will ensure that each daughter cell receives one copy of the chromosome. The defining biochemical feature of this checkpoint is the stimulation of the anaphase-promoting complex by M-phase cyclin-CDK complexes, which in turn causes the proteolytic destruction of cyclins and proteins that hold the sister chromatids together.

<span class="mw-page-title-main">Separase</span> Mammalian protein found in Homo sapiens

Separase, also known as separin, is a cysteine protease responsible for triggering anaphase by hydrolysing cohesin, which is the protein responsible for binding sister chromatids during the early stage of anaphase. In humans, separin is encoded by the ESPL1 gene.

<span class="mw-page-title-main">Cohesin</span> Protein complex that regulates the separation of sister chromatids during cell division

Cohesin is a protein complex that mediates sister chromatid cohesion, homologous recombination, and DNA looping. Cohesin is formed of SMC3, SMC1, SCC1 and SCC3. Cohesin holds sister chromatids together after DNA replication until anaphase when removal of cohesin leads to separation of sister chromatids. The complex forms a ring-like structure and it is believed that sister chromatids are held together by entrapment inside the cohesin ring. Cohesin is a member of the SMC family of protein complexes which includes Condensin, MukBEF and SMC-ScpAB.

Structural maintenance of chromosomes protein 1A (SMC1A) is a protein that in humans is encoded by the SMC1A gene. SMC1A is a subunit of the cohesin complex which mediates sister chromatid cohesion, homologous recombination and DNA looping. In somatic cells, cohesin is formed of SMC1A, SMC3, RAD21 and either SA1 or SA2 whereas in meiosis, cohesin is formed of SMC3, SMC1B, REC8 and SA3.

<span class="mw-page-title-main">CENPA</span> Protein-coding gene in the species Homo sapiens

Centromere protein A, also known as CENPA, is a protein which in humans is encoded by the CENPA gene. CENPA is a histone H3 variant which is the critical factor determining the kinetochore position(s) on each chromosome in most eukaryotes including humans.

<span class="mw-page-title-main">RAD21</span> Protein-coding gene in humans

Double-strand-break repair protein rad21 homolog is a protein that in humans is encoded by the RAD21 gene. RAD21, an essential gene, encodes a DNA double-strand break (DSB) repair protein that is evolutionarily conserved in all eukaryotes from budding yeast to humans. RAD21 protein is a structural component of the highly conserved cohesin complex consisting of RAD21, SMC1A, SMC3, and SCC3 [ STAG1 (SA1) and STAG2 (SA2) in multicellular organisms] proteins, involved in sister chromatid cohesion.

<span class="mw-page-title-main">SMC3</span> Protein-coding gene in humans

Structural maintenance of chromosomes protein 3 (SMC3) is a protein that in humans is encoded by the SMC3 gene. SMC3 is a subunit of the Cohesin complex which mediates sister chromatid cohesion, homologous recombination and DNA looping. Cohesin is formed of SMC3, SMC1, RAD21 and either SA1 or SA2. In humans, SMC3 is present in all cohesin complexes whereas there are multiple paralogs for the other subunits.

<span class="mw-page-title-main">STAG2</span> Protein-coding gene in humans

Cohesin subunit SA-2 (SA2) is a protein that in humans is encoded by the STAG2 gene. SA2 is a subunit of the Cohesin complex which mediates sister chromatid cohesion, homologous recombination and DNA looping. In somatic cells cohesin is formed of SMC3, SMC1, RAD21 and either SA1 or SA2 whereas in meiosis, cohesin is formed of SMC3, SMC1B, REC8 and SA3.

<span class="mw-page-title-main">WAPAL</span> Protein-coding gene in the species Homo sapiens

Wings apart-like protein homolog (WAPL) is a protein that in humans is encoded by the WAPAL gene. WAPL is a key regulator of the Cohesin complex which mediates sister chromatid cohesion, homologous recombination and DNA looping. Cohesin is formed of SMC3, SMC1, RAD21 and either SA1 or SA2. Cohesin has a ring-like arrangement and it is thought that it associates with the chromosome by entrapping it whether as a loop of DNA, a single strand or a pair of sister chromosomes. WAPL forms a complex with PDS5A or PDS5B and releases cohesin from DNA by opening the interface between SMC3 and RAD21.

Sister chromatid cohesion protein PDS5 homolog B(PDS5B) is a protein that in humans is encoded by the PDS5B gene. It is a regulatory subunit of the Cohesin complex which mediates sister chromatid cohesion, homologous recombination and DNA looping. The core cohesin complex is formed of SMC3, SMC1, RAD21 and either SA1 or SA2. PDS5 associates with WAPL to stimulate the release of cohesin from DNA but during DNA replication PDS5 promotes acetylation of SMC3 by ESCO1 and ESCO2.

N-acetyltransferase ESCO2, also known as establishment of cohesion 1 homolog 2 or ECO1 homolog 2, is an enzyme that in humans is encoded by the ESCO2 gene.

Sister chromatid cohesion refers to the process by which sister chromatids are paired and held together during certain phases of the cell cycle. Establishment of sister chromatid cohesion is the process by which chromatin-associated cohesin protein becomes competent to physically bind together the sister chromatids. In general, cohesion is established during S phase as DNA is replicated, and is lost when chromosomes segregate during mitosis and meiosis. Some studies have suggested that cohesion aids in aligning the kinetochores during mitosis by forcing the kinetochores to face opposite cell poles.

<span class="mw-page-title-main">SMC1B</span> Protein-coding gene in the species Homo sapiens

Structural maintenance of chromosomes protein 1B (SMC-1B) is a protein that in humans is encoded by the SMC1B gene. SMC proteins engage in chromosome organization and can be broken into 3 groups based on function which are cohesins, condensins, and DNA repair. SMC-1B belongs to a family of proteins required for chromatid cohesion and DNA recombination during meiosis and mitosis. SMC1B protein appears to participate with other cohesins REC8, STAG3 and SMC3 in sister-chromatid cohesion throughout the whole meiotic process in human oocytes.
