Function
ABL2 is a cytoplasmic tyrosine kinase which is carefully accompanying to but audible from ABL1. The affinity of the proteins includes the tyrosine kinase domains and extends amino-terminal to cover the SH2 and SH3 domains. ABL2 is bidding in both accustomed and bump cells. The ABL2 gene artefact is bidding as two variants address altered amino termini, both about 12-kb in length.
Abl2 (also accepted as ARG (ABL Accompanying Gene)) is a affiliate of the Abelson ancestors of non-receptor tyrosine kinase. ABL2 shares a top amount of arrangement attention with cABL and has agnate area alignment absolute an N-terminal SH3–SH2 kinase area assemblage followed by a C-terminal area absolute advancing sites for SH3 domains, F-actin and microtubules. Through its interactions with the cytoskeleton ABL2 plays a role in murine neurulation and it is appropriate for adhesion-dependent neurite aberration and synapse/dendrite stability. ABL2 has aswell a role in fibroblastic- and epithelial corpuscle adherence and migration. ABL2 shares a amount of cellular authoritative functions with cABL. Targeted disruption of the cAbl gene in mice resulted in pleiotropic phenotypes including runtedness, top perinatal lethality, susceptibility to infections, and allowed deficiencies. In contrast, homozygous Abl2 knockout mice are advantageous and affectation no immune-deficient phenotypes. However, affirmation for overlapping roles of cAbl and Abl2 was acquired by allegory mice amiss for both genes, which appear that both proteins are appropriate for accustomed abrasion development. Abl/Abl2-/- mice die about beginning day 10.5, and the embryos affectation bleeding in the pericardial sac, affectation bargain admeasurement and cytokine assembly in acknowledgment to TCR dispatch and showed a decidedly broken antibiotic production.
