Alpha-actinin-1 is a protein that in humans is encoded by the ACTN1 gene. [5]
Alpha actinins belong to the spectrin gene superfamily which represents a diverse group of cytoskeletal proteins, including the alpha and beta spectrins and dystrophins. Alpha-actinin-1 is an F-actin cross-linking protein – a bundling protein that is thought to anchor actin to a number of intracellular structures. [6] Alpha-actinin-1 is a non-muscle cytoskeletal isoform found along microfilament bundles and adherens-type junctions, where it is involved in binding actin to the membrane. In contrast, skeletal, cardiac, and smooth muscle isoforms are localized to the Z-disc and analogous dense bodies, where they help anchor the myofibrillar actin filaments. [7]
Alpha-actinin-1 has been shown to interact with:
Protein 4.1,, is a protein associated with the cytoskeleton that in humans is encoded by the EPB41 gene. Protein 4.1 is a major structural element of the erythrocyte membrane skeleton. It plays a key role in regulating membrane physical properties of mechanical stability and deformability by stabilizing spectrin-actin interaction. Protein 4.1 interacts with spectrin and short actin filaments to form the erythrocyte membrane skeleton. Mutations of spectrin and protein 4.1 are associated with elliptocytosis or spherocytosis and anemia of varying severity.
Filamin A, alpha (FLNA) is a protein that in humans is encoded by the FLNA gene.
LIM domain kinase 1 is an enzyme that in humans is encoded by the LIMK1 gene.
Sodium-hydrogen exchange regulatory cofactor NHE-RF2 (NHERF-2) also known as tyrosine kinase activator protein 1 (TKA-1) or SRY-interacting protein 1 (SIP-1) is a protein that in humans is encoded by the SLC9A3R2 gene.
Disintegrin and metalloproteinase domain-containing protein 12 is an enzyme that in humans is encoded by the ADAM12 gene. ADAM12 has two splice variants: ADAM12-L, the long form, has a transmembrane region and ADAM12-S, a shorter variant, is soluble and lacks the transmembrane and cytoplasmic domains.
Alpha II-spectrin, also known as Spectrin alpha chain, brain is a protein that in humans is encoded by the SPTAN1 gene. Alpha II-spectrin is expressed in a variety of tissues, and is highly expressed in cardiac muscle at Z-disc structures, costameres and at the sarcolemma membrane. Mutations in alpha II-spectrin have been associated with early infantile epileptic encephalopathy-5, and alpha II-spectrin may be a valuable biomarker for Guillain–Barré syndrome and infantile congenital heart disease.
Alpha-adducin is a protein that in humans is encoded by the ADD1 gene.
Vasodilator-stimulated phosphoprotein is a protein that in humans is encoded by the VASP gene.
Alpha-actinin-2 is a protein which in humans is encoded by the ACTN2 gene. This gene encodes an alpha-actinin isoform that is expressed in both skeletal and cardiac muscles and functions to anchor myofibrillar actin thin filaments and titin to Z-discs.
Alpha-actinin-4 is a protein that in humans is encoded by the ACTN4 gene.
Zyxin is a protein that in humans is encoded by the ZYX gene.
Alpha-1-syntrophin is a protein that in humans is encoded by the SNTA1 gene. Alpha-1 syntrophin is a signal transducing adaptor protein and serves as a scaffold for various signaling molecules. Alpha-1 syntrophin contains a PDZ domain, two Pleckstrin homology domain and a 'syntrophin unique' domain.
Beta-adducin is a protein that in humans is encoded by the ADD2 gene.
Ena/VASP-like protein is a member of the Ena/VASP family of proteins that in humans is encoded by the EVL gene.
Serine/threonine-protein kinase MRCK alpha is an enzyme that in humans is encoded by the CDC42BPA gene.
LIM and SH3 domain protein 1 is a protein that in humans is encoded by the LASP1 gene.
Four and a half LIM domains protein 3 is a protein that in humans is encoded by the FHL3 gene.
Spectrin, beta, non-erythrocytic 4, also known as SPTBN4, is a protein that in humans is encoded by the SPTBN4 gene.
Spectrin, beta, non-erythrocytic 5 also known as SPTBN5 is a protein that in humans is encoded by the SPTBN5 gene. SPTBN5 belongs to the spectrin family of cytoskeletal proteins.
