CC -!- FUNCTION: May act in negative regulation of cell growth and
CC transformation by interacting with nonreceptor tyrosine kinases ABL1
CC and/or ABL2. In vitro, at least isoform 2 and isoform 4 suppress the
CC transforming activity of Abelson murine leukemia virus (v-Abl) after
CC overexpression in fibroblasts. May play a role in regulation EGF-
CC induced Erk pathway activation. Involved in cytoskeletal reorganization
CC and EGFR signaling. Together with EPS8 participates in transduction of
CC signals from Ras to Rac. In vitro, a trimeric complex of ABI1, EPS8 and
CC SOS1 exhibits Rac specific guanine nucleotide exchange factor (GEF)
CC activity and ABI1 seems to act as an adapter in the complex. Regulates
CC ABL1/c-Abl-mediated phosphorylation of ENAH. Recruits WASF1 to
CC lamellipodia and there seems to regulate WASF1 protein level. In brain,
CC seems to regulate the dendritic outgrowth and branching as well as to
CC determine the shape and number of synaptic contacts of developing
CC neurons. {ECO:0000269|PubMed:10499589, ECO:0000269|PubMed:11526477,

CC -!- SUBUNIT: Interacts with ENAH, Abelson murine leukemia virus V-ABL,
CC ABL1, STX1A, SNAP25, VAMP2, and through its N-terminus with WASF1. Part
CC of a complex consisting of ABI1, STX1A and SNAP25. Part of a complex
CC consisting of ABI1, EPS8 and SOS1. Interacts with EPS8, SOS1, SOS2,
CC GRB2, SPTA1, and the first SH3 domain of NCK1 (By similarity).
CC Component of the WAVE2 complex composed of ABI1, CYFIP1/SRA1,
CC NCKAP1/NAP1 (NCKAP1l/HEM1 in hematopoietic cells) and WASF2/WAVE2.
CC Interacts (via SH3 domain) with SHANK2 and SHANK3, but not SHANK1; the
CC interaction is direct. Interacts with the heterodimer MYC:MAX; the
CC interaction may enhance MYC:MAX transcriptional activity. Interacts
CC with FNBP1L (via the SH3 domain), WASF2, and CDC42, but only in the
CC presence of FNBP1L (By similarity). {ECO:0000250,

CC prominently expressed in the neocortex, hippocampus and dentate gyrus.
CC {ECO:0000269|PubMed:10995551, ECO:0000269|PubMed:7590237}.
CC -!- DEVELOPMENTAL STAGE: Detected at 10 dpc and 12 dpc in developing brain,
CC but does not appear more prominent in the neuroepithelium compared to
CC the surrounding tissue. {ECO:0000269|PubMed:10995551}.
CC -!- DOMAIN: The t-SNARE coiled-coil homology domain is necessary and
CC sufficient for interaction with STX1A.
CC -!- PTM: Phosphorylated on tyrosine residues after serum stimulation or
CC induction by v-Abl. Seems to be phosphorylated at Tyr-53 by ABL1,
CC required for nuclear but not for synaptic localization (By similarity).
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the ABI family. {ECO:0000305}.
