FAMILY

CATEGORY

regulatory , transcription factor

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm,organelle,mitochondria
	intracellular,nucleus,chromatin/chromosome

basic FUNCTION	substrate of the antigen recepto-coupled tyrosine kinase, playing a role in antigen receptor signaling for both clonal expansion and deletion in lymphoid cells
	substrate of caspase 3 (degradation in a caspase-dependent manner during apoptosis)
	is a central regulator of cytoskeleton remodeling that controls lymphocyte trafficking and homing and significantly influences the tissue invasion and infiltration in CLL
	cytoskeletal interactor in the B-cell receptor (BCR) signaling pathway whose phosphorylation correlates with prognosis in Chronic Lymphocytic Leukemia (CLL)
	is important for the activation of GTPases and integrins, and mediates signaling downstream of many receptors including BCR, TCR, and CXCR4

CELLULAR PROCESS

nucleotide, transcription, regulation

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

signal transduction

a component

forms a multiprotein complex with ANKRD54 and LYN in erythroid cells (Samuels 2009)

INTERACTION

DNA

binding

RNA

small molecule

protein	binding to HAX1 and to the SH2 and SH3 domains of HS1BP3
	HS1BP3 regulates apoptosis via HCLS1 and stimulates JUN-mediated transcription
