CC -!- FUNCTION: Could be a T-cell-specific adapter protein involved in the
CC control of T-cell activation. May play a role in the CD4-p56-LCK-
CC dependent signal transduction pathway. Could also play an important
CC role in normal and pathological angiogenesis. Could be an adapter
CC protein that facilitates and regulates interaction of KDR with effector
CC proteins important to endothelial cell survival and proliferation.
CC -!- SUBUNIT: Interacts with KDR. Interacts with TXK and ITK (By
CC similarity). {ECO:0000250}.

CC -!- TISSUE SPECIFICITY: Expression limited to tissues of the immune system
CC and, in particular, activated T-cells. Expressed in peripheral blood
CC leukocytes, thymus and spleen. Much lower expression or undetectable,
CC in brain, placenta, skeletal muscle, prostate, testis, ovary, small
CC intestine, and colon. Expressed at low levels in unstimulated T-cells,
CC but not expressed in normal resting or activated B-cells. According to
CC PubMed:10692392, expression is not restricted to activated T-cells, but
CC strongly expressed in blood cell lineages, the endothelium and other
CC cell and tissue types, such as heart, lung, and liver.
CC -!- INDUCTION: Rapidly induced after activation of T-cells. However, the
CC gene continues to be expressed in long-term cultures of activated T-
CC cells.
CC -!- PTM: Phosphorylated on tyrosine residues.
CC -!- SEQUENCE CAUTION:
