Expressed only in tissues and cells of hematopoietic origin.

Substrate of the antigen receptor-coupled tyrosine kinase. Plays a role in antigen receptor signaling for both clonal expansion and deletion in lymphoid cells. Directly associates with HAX-1, through binding to its C-terminal region. May also be involved in the regulation of gene expression.

Research Backgrounds


Substrate of the antigen receptor-coupled tyrosine kinase. Plays a role in antigen receptor signaling for both clonal expansion and deletion in lymphoid cells. May also be involved in the regulation of gene expression.


Phosphorylated by FES (By similarity). Phosphorylated by LYN, FYN and FGR after cross-linking of surface IgM on B-cells. Phosphorylation by LYN, FYN and FGR requires prior phosphorylation by SYK or FES.

Subcellular Location:

Membrane>Peripheral membrane protein. Cytoplasm. Mitochondrion.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Tissue Specificity:

Expressed only in tissues and cells of hematopoietic origin.

Subunit Structure:

Associates with the SH2 and SH3 domains of LCK. Binding to he LCK SH3 domain occurs constitutively, while binding to the LCK SH2 domain occurs only upon TCR stimulation. A similar binding pattern was observed with LYN, but not with FYN in which the FYN SH2 region associates upon TCR stimulation but the FYN SH3 region does not associate regardless of TCR stimulation. Directly associates with HAX1, through binding to its C-terminal region. Interacts with HS1BP3. Interacts with FES/FPS (By similarity). Interacts (via SH2 domain) with FGR. Forms a multiprotein complex with LYN and ANKRD54 (By similarity).
