Protein-coding gene in the species Homo sapiens
Lymphocyte cytosolic protein 2 (SH2 domain containing leukocyte protein of 76kDa), also known as LCP2 or SLP-76, is a signal-transducing adaptor protein expressed in T cells and myeloid cells and is important in the signaling of T-cell receptors (TCRs).[5][6] As an adaptor protein, SLP-76 does not have catalytic functions, primarily binding other signaling proteins to form larger signaling complexes.[7] It is a key component of the signaling pathways of receptors with immunoreceptor tyrosine-based activation motifs (ITAMs) such as T-cell receptors, its precursors, and receptors for the Fc regions of certain antibodies.[7] SLP-76 is expressed in T-cells and related lymphocytes like natural killer cells.[8]
