ABI2 Protein Overview: Sequence, Structure, Function and Protein Interaction

ABI2 Protein Overview

ABI2 reagents

The ABL protein (ABL1; 189980) is the cellular homolog of the Abl oncogene product of Abelson murine leukemia virus. ABL is a tyrosine kinase that may regulate signal transduction events in the cytoplasm and processes in the nucleus. The transforming Abl proteins are constitutively active tyrosine kinases primarily localized in the cytoplasm. They are repressed by SH3 domains and possibly by other regions.
