Abi

Drosophila melanogaster

Abelson interacting protein (Abi) encodes a protein that interacts with the non-receptor tyrosine kinase encoded by Abl. It contributes to the regulation of actin cytoskeleton organization. It is involved in multiple actin dependent processes including cell adhesion, cell morphogenesis, oogenesis, muscle attachment and axogenesis.

Abi1

Homo sapiens

This gene encodes a member of the Abelson-interactor family of adaptor proteins. These proteins facilitate signal transduction as components of several multiprotein complexes, and regulate actin polymerization and cytoskeletal remodeling through interactions with Abelson tyrosine kinases. The encoded protein plays a role in macropinocytosis as a component of the WAVE2 complex, and also forms a complex with EPS8 and SOS1 that mediates signal transduction from Ras to Rac. This gene may play a role in the progression of several malignancies including melanoma, colon cancer and breast cancer, and a t(10;11) chromosomal translocation involving this gene and the MLL gene has been associated with acute myeloid leukemia. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 14.

Ahi1

Rattus norvegicus

Predicted to enable identical protein binding activity. Involved in several processes, including embryonic brain development; negative regulation of glucose import; and response to food. Predicted to be located in adherens junction; microtubule organizing center; and photoreceptor cell cilium. Predicted to be part of MKS complex. Predicted to be active in ciliary basal body. Human ortholog(s) of this gene implicated in Joubert syndrome 3; Joubert syndrome 4; and autism spectrum disorder. Orthologous to human AHI1 (Abelson helper integration site 1); INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; 3,3',4,4',5-pentachlorobiphenyl; 3,3',5,5'-tetrabromobisphenol A.

mig-10

Caenorhabditis elegans

Enables SH3 domain binding activity. Involved in several processes, including cell migration; cell projection organization; and egg-laying behavior. Located in neuronal cell body membrane; plasma membrane bounded cell projection; and presynaptic cytosol. Part of filamentous actin. Expressed in hermaphrodite gonad; neurons; and tail. Is an ortholog of human RAPH1 (Ras association (RalGDS/AF-6) and pleckstrin homology domains 1).

Abl2

Homo sapiens

This gene encodes a member of the Abelson family of nonreceptor tyrosine protein kinases. The protein is highly similar to the c-abl oncogene 1 protein, including the tyrosine kinase, SH2 and SH3 domains, and it plays a role in cytoskeletal rearrangements through its C-terminal F-actin- and microtubule-binding sequences. This gene is expressed in both normal and tumor cells, and is involved in translocation with the ets variant 6 gene in leukemia. Multiple alternatively spliced transcript variants encoding different protein isoforms have been found for this gene. [provided by RefSeq, Nov 2009]

Sorbs2

Homo sapiens

Arg and c-Abl represent the mammalian members of the Abelson family of non-receptor protein-tyrosine kinases. They interact with the Arg/Abl binding proteins via the SH3 domains present in the carboxy end of the latter group of proteins. This gene encodes the sorbin and SH3 domain containing 2 protein. It has three C-terminal SH3 domains and an N-terminal sorbin homology (SoHo) domain that interacts with lipid raft proteins. The subcellular localization of this protein in epithelial and cardiac muscle cells suggests that it functions as an adapter protein to assemble signaling complexes in stress fibers, and that it is a potential link between Abl family kinases and the actin cytoskeleton. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]
