HS1 (HCLS1, LckBP1, p75) is a protein kinase substrate that is expressed only in tissues and cells of hematopoietic origin. HS1 contains four cortactin repeats and a single SH3 domain. This intracellular protein is phosphorylated following immune receptor activation, which promotes recruitment of HS1 to the immune synapse. Phosphorylation of HS1 is required to regulate actin dynamics and provide docking sites for many other signaling molecules, such as Vav1 and PLCγ1. HS1 also plays an important role in platelet activation.

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.
