The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
IHC-P: 1/100 - 1/500. Antigen retrieval with citrate buffer is not essential but may optimise staining.
The Ab is likely to work also with frozen sections.
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
May act in negative regulation of cell growth and transformation by interacting with nonreceptor tyrosine kinases ABL1 and/or ABL2. May play a role in regulation of EGF-induced Erk pathway activation. Involved in cytoskeletal reorganization and EGFR signaling. Together with EPS8 participates in transduction of signals from Ras to Rac. In vitro, a trimeric complex of ABI1, EPS8 and SOS1 exhibits Rac specific guanine nucleotide exchange factor (GEF) activity and ABI1 seems to act as an adapter in the complex. Regulates ABL1/c-Abl-mediated phosphorylation of ENAH. Recruits WASF1 to lamellipodia and there seems to regulate WASF1 protein level.
Widely expressed, with highest expression in brain.
Note=A chromosomal aberration involving ABI1 is a cause of acute leukemias. Translocation t(10;11)(p11.2;q23) with MLL. ABI1 isoform 2 was found to be present in acute leukemia MLL-ABI1 fusion transcript.
Belongs to the ABI family. Contains 1 SH3 domain. Contains 1 t-SNARE coiled-coil homology domain.
The t-SNARE coiled-coil homology domain is necessary and sufficient for interaction with STX1A.
In vitro substrate for v-Abl (By similarity). Phosphorylated on tyrosine residues after serum stimulation or induction by v-Abl.
Cytoplasm. Nucleus. Cell projection > lamellipodium. Cell projection > filopodium. Cell projection > growth cone. Cell junction > synapse > synaptosome. Cytoplasm > cytoskeleton. Localized to protruding lamellipodia and filopodia tips. Also localized to neuronal growth cones and synaptosomes.
