phospho-c-ABL1+2 (Tyr393+439),***酸化非受体酪氨酸激酶c-Abl抗体Subunit:
Interacts with SORBS1 following insulin stimulation. Found in a trimolecular complex containing CDK5 and CABLES1. Interacts with CABLES1 and PSTPIP1. Interacts with ZDHHC16, ITGB1 and HCK (By similarity). Interacts with INPPL1/SHIP2. Interacts with the 14-3-3 proteins, YWHAB, YWHAE, YWHAG, YWHAH, SFN AND YWHAZ; the interaction with 14-3-3 proteins requires phosphorylation on Thr-735 and, sequesters ABL1 into the cytoplasm. Interacts with ABI1, ABI2, BCR, CRK, FGR, FYN, HCK, LYN, PSMA7 RAD9A, RAD51, RAD52, TP73 and WASF3. A complex made of ABL1, CTTN and MYLK regulates cortical actin-based cytoskeletal rearrangement critical to sphingosine 1-phosphate (S1P)-mediated endothelial cell (EC) barrier enhancement.

Subcellular Location:
Cytoplasm, cytoskeleton. Nucleus. Mitochondrion. Note=Shuttles between the nucleus and cytoplasm depending on environmental signals. Sequestered into the cytoplasm through interaction with 14-3-3 proteins. Localizes to mitochondria in response to oxidative stress. Isoform IB: Nucleus membrane; Lipid-anchor. Note=The myristoylated c-ABL protein is reported to be nuclear.

Tissue Specificity:
Widely expressed.

Post-translational modifications:
Acetylated at Lys-711 by EP300 which promotes the cytoplasmic translocation.
Phosphorylation at Tyr-70 by members of the SRC family of kinases disrupts SH3 domain-based autoinhibitory interactions and intermolecular associations, such as that with ABI1, and also enhances kinase activity. Phosphorylation at Tyr-226 and Tyr-393 correlate with increased activity. DNA damage-induced activation of ABL1 requires the function of ATM and Ser-446 phosphorylation. Phosphorylation at Ser-569 has been attributed to a CDC2-associated kinase and is coupled to cell division. Phosphorylation at Ser-618 and Ser-619 by PAK2 increases binding to CRK and reduces binding to ABI1. Phosphorylation on Thr-735 is required for binding 14-3-3 proteins for cytoplasmic translocation. Phosphorylated by PRKDC.
Polyubiquitinated. Polyubiquitination of ABL1 leads to degradation.
Isoform IB is myristoylated on Gly-2.

DISEASE:
Note=A chromosomal aberration involving ABL1 is a cause of chronic myeloid leukemia. Translocation t(9;22)(q34;q11) with BCR. The translocation produces a BCR-ABL found also in acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL).

Similarity:
Belongs to the protein kinase superfamily. Tyr protein kinase family. ABL subfamily.
Contains 1 protein kinase domain.
Contains 1 SH2 domain.
Contains 1 SH3 domain.

Gene ID:
25

非受体酪氨酸激酶c-Abl广泛表达于各组织细胞中,c-Abl是非受体酪氨酸激酶Src家族的一个成员。在生理状态下,它可以定位于多个亚细胞结构(如细胞核、细胞质、线粒体等)中并呈现不同功能。经研究认为,细胞核内的c-Abl在细胞凋亡调控以及DNA损伤修复过程中起重要作用,而胞质中的c-Abl则与细胞黏附、细胞分化及氧化应激有关联，该蛋白主要用于细胞凋亡的研究。
