FXYD domain-containing ion transport regulator 5 also named dysadherin (human) or RIC (mouse) is a protein that in humans is encoded by the FXYD5 gene. [5]
This gene encodes a member of a family of small membrane proteins that share a 35-amino acid signature sequence domain, beginning with the sequence PFXYD and containing 7 invariant and 6 highly conserved amino acids. The approved human gene nomenclature for the family is FXYD-domain containing ion transport regulator. Mouse FXYD5 has been termed RIC (Related to Ion Channel). FXYD2, also known as the gamma subunit of the Na,K-ATPase, regulates the properties of that enzyme. FXYD1 (phospholemman), FXYD2 (gamma), FXYD3 (MAT-8), FXYD4 (CHIF), and FXYD5 (RIC) have been shown to induce channel activity in experimental expression systems. Transmembrane topology has been established for two family members (FXYD1 and FXYD2), with the N-terminus extracellular and the C-terminus on the cytoplasmic side of the membrane. This gene product, FXYD5, has not been characterized as a protein. Two transcript variants have been found for this gene, and they are both predicted to encode the same protein. [5]
Dysadherin is the gamma5 subunit of the human Na,K-ATPase. Of all the FXYD members, dysadherin is the only member that has a large extracellular sequence of 140 amino acids. Dysadherin has been observed to be over-expressed on the surface of cells that have down regulated levels of surface E-cadherin. CCL2 (bone homing cytokine)is a protein that is highly affected by silencing dysadherin expression. Dysadherin interferes with cell adhesion via beta1 subunit interactions. [6] Dysadherin is a target for an extracellular antibody drug conjugate where the antibody to dysadherin is attached to a cardiac glycoside. [7]
Dysadherin has been found to be a marker for metastatic cancers and found up-regulated in multiple cancer types. [7]
Cadherins (named for "calcium-dependent adhesion") are cell adhesion molecules important in forming adherens junctions that let cells adhere to each other. Cadherins are a class of type-1 transmembrane proteins, and they depend on calcium (Ca2+) ions to function, hence their name. Cell-cell adhesion is mediated by extracellular cadherin domains, whereas the intracellular cytoplasmic tail associates with numerous adaptors and signaling proteins, collectively referred to as the cadherin adhesome.
Catenins are a family of proteins found in complexes with cadherin cell adhesion molecules of animal cells. The first two catenins that were identified became known as α-catenin and β-catenin. α-Catenin can bind to β-catenin and can also bind filamentous actin (F-actin). β-Catenin binds directly to the cytoplasmic tail of classical cadherins. Additional catenins such as γ-catenin and δ-catenin have been identified. The name "catenin" was originally selected because it was suspected that catenins might link cadherins to the cytoskeleton.
Matrilysin also known as matrix metalloproteinase-7 (MMP-7), pump-1 protease (PUMP-1), or uterine metalloproteinase is an enzyme in humans that is encoded by the MMP7 gene. The enzyme has also been known as matrin, putative metalloproteinase-1, matrix metalloproteinase pump 1, PUMP-1 proteinase, PUMP, metalloproteinase pump-1, putative metalloproteinase, MMP). Human MMP-7 has a molecular weight around 30 kDa.
Shekel Somatostatin receptor type 3 is a protein that in humans is encoded by the SSTR3 gene.
Cadherin-3, also known as P-Cadherin, is a protein that in humans is encoded by the CDH3 gene.
Epithelial cell adhesion molecule (EpCAM), also known as CD326 among other names, is a transmembrane glycoprotein mediating Ca2+-independent homotypic cell–cell adhesion in epithelia. EpCAM is also involved in cell signaling, migration, proliferation, and differentiation. Additionally, EpCAM has oncogenic potential via its capacity to upregulate c-myc, e-fabp, and cyclins A & E. Since EpCAM is expressed exclusively in epithelia and epithelial-derived neoplasms, EpCAM can be used as diagnostic marker for various cancers. It appears to play a role in tumorigenesis and metastasis of carcinomas, so it can also act as a potential prognostic marker and as a potential target for immunotherapeutic strategies.
Zinc finger protein SNAI1 is a protein that in humans is encoded by the SNAI1 gene. Snail is a family of transcription factors that promote the repression of the adhesion molecule E-cadherin to regulate epithelial to mesenchymal transition (EMT) during embryonic development.
Interleukin 11 receptor, alpha subunit is a subunit of the interleukin 11 receptor. IL11RA is its human gene.
Cadherin-11 is a protein that in humans is encoded by the CDH11 gene.
Cadherin-4 is a protein that in humans is encoded by the CDH4 gene.
Cadherin-6 is a protein that in humans is encoded by the CDH6 gene.
Cadherin-15 is a protein that in humans is encoded by the CDH15 gene.
Cadherin-17 is a protein that in humans is encoded by the CDH17 gene.
40S ribosomal protein S12 is a protein that in humans is encoded by the RPS12 gene.
Tetraspanin-8 is a protein that in humans is encoded by the TSPAN8 gene.
Condensin complex subunit 2 also known as chromosome-associated protein H (CAP-H) or non-SMC condensin I complex subunit H (NCAPH) is a protein that in humans is encoded by the NCAPH gene. CAP-H is a subunit of condensin I, a large protein complex involved in chromosome condensation. Abnormal expression of NCAPH may be linked to various types of carcinogenesis as a prognostic indicator.
Protocadherin-17 is a protein that in humans is encoded by the PCDH17 gene.
FXYD domain-containing ion transport regulator 3 is a protein that in humans is encoded by the FXYD3 gene.
Ubiquinol-cytochrome c reductase, Rieske iron-sulfur polypeptide 1, also known as UQCRFS1, Rieske iron-sulfur (Fe-S) protein, Cytochrome b-c1 complex subunit 5, or Complex III subunit 5 is a protein which in humans is encoded by the UQCRFS1 gene. UQCRFS1 is a subunit of the respiratory chain protein Ubiquinol Cytochrome c Reductase, which consists of the products of one mitochondrially encoded gene, MTCYTB and ten nuclear genes UQCRC1, UQCRC2, Cytochrome C1, UQCRFS1, UQCRB,UQCRQ, UQCRH, UCRC, and UQCR.
Cadherin-1 or Epithelial cadherin(E-cadherin), is a protein that in humans is encoded by the CDH1 gene. Mutations are correlated with gastric, breast, colorectal, thyroid, and ovarian cancers. CDH1 has also been designated as CD324. It is a tumor suppressor gene.
