Summary

LCP2 (lymphocyte cytosolic protein 2, HGNC:6529) is a protein-coding gene on chromosome 5q35.1, encoding Lymphocyte cytosolic protein 2 (Q13094). Adapter protein primarily involved in signaling pathways within T-cells, as well as other immune cells such as platelets, mast cells, and natural killer (NK) cells.

This gene encodes an adapter protein that acts as a substrate of the T cell antigen receptor (TCR)-activated protein tyrosine kinase pathway. The encoded protein associates with growth factor receptor bound protein 2, and is thought to play a role TCR-mediated intracellular signal transduction. A similar protein in mouse plays a role in normal T-cell development and activation. Mice lacking this gene show subcutaneous and intraperitoneal fetal hemorrhaging, dysfunctional platelets and impaired viability.

  • Data suggest that SLP-76 may play a role in signaling pathways by interacting with the p85 subunit of phosphoinositide 3-kinase (PI3K). (PMID:15388330)
  • SLP-76 need not interact with SH3(PLC) to activate PLC-gamma1, and the P-I region of SLP-76 serves a structural role that is sequence-independent and is not directly related to protein-protein interactions (PMID:15623534)
  • Data show that the adaptor molecules LAT and SLP-76 are specifically targeted by Yersinia to inhibit T cell activation. (PMID:15699071)
  • TCR-induced association of Vav3 with SLP-76 is required for its membrane/IS localization and function (PMID:15708849)
  • the Lck binding region of SLP-76 is essential for T cell antigen receptor signaling and normal T cell development and function (PMID:16354835)
  • In T cells all SLP-76 proteins are in a approximately 400 kDa complex with the small adaptor protein Grb2-like adaptor protein Gads. (PMID:16356554)
  • findings show that retinoic acid(RA) induced the expression of SLP-76, which when co-expressed with an RA-induced receptor, c-FMS, enhanced RA-induced cell differentiation and G0 cell cycle arrest (PMID:16439309)

  • The P-I region deletion disrupted Vav association and reduced SLP-76-associated kinase activity. (PMID:17148460)
  • The integrity of T-cell receptor signaling in vivo is sustained both by strong selection of SLP-76 for the Gads C-SH3 domain and by a capacity to buffer intrinsic crossreactivity. (PMID:17235283)
  • phosphorylation of the adaptor molecule SLP-76 is essential for recruitment of the exchange factor Vav leading to Ca(2+) flux and IL-2 production (PMID:17237383)
  • Required for activation of IL-2-inducible T cell kinase (ITK); furthermore, an ongoing physical interaction between SLP-76 and ITK is required to maintain ITK in an active conformation. (PMID:17420479)
  • study reports that T cell costimulation by the integrin VLA-4 (alpha4beta1) required SLP-76 domains implicated in microcluster assembly (PMID:18549800)

Function. Adapter protein primarily involved in signaling pathways within T-cells, as well as other immune cells such as platelets, mast cells, and natural killer (NK) cells. Plays a crucial role for transducing signal from the T-cell receptor (TCR) after antigen recognition leading to T-cell activation. Mechanistically, once phosphorylated by the kinase ZAP70, mediates interactions with the guanine-nucleotide exchange factor VAV1, the adapter protein NCK and the kinase ITK. In turn, stimulates the activation of PKC-theta/PRKCQ and NF-kappa-B transcriptional activity in response to CD3 and CD28 costimulation. Also plays an essential role in AGER-induced signaling pathways including p38 MAPK and ERK1/2 activation leading to cytokine release and pro-inflammatory responses.

Subunit / interactions. Interacts with SLA. Interacts with CBLB. Interacts with GRB2. Interacts with SHB. Interacts with PRAM1. Interacts (via SH2 domain) with CD6 (via tyrosine phosphorylated C-terminus). Interacts with FYB1 and the phosphorylated form of FYB2. Interacts with 14-3-3 adapter/YWHAZ; this phosphorylation leads to YWHAZ proteolytic degradation. Interacts with VAV1; this interaction plays a role in TCR-mediated cytokine production. Interacts with AGER; this interaction plays an important role in AGER-mediated pro-inflammatory responses and cytokine release.

Subcellular location. Cytoplasm.

Tissue specificity. Highly expressed in spleen, thymus and peripheral blood leukocytes. Highly expressed also in T-cell and monocytic cell lines, expressed at lower level in B-cell lines. Not detected in fibroblast or neuroblastoma cell lines.

Post-translational modifications. Phosphorylated after T-cell receptor activation by ZAP70, ITK and TXK, which leads to the up-regulation of Th1 preferred cytokine IL-2. SYK-dependent phosphorylation is required for recruitment of PI3K signaling components.

Disease relevance. Immunodeficiency 81 (IMD81) [MIM:619374] An autosomal recessive disorder characterized by recurrent infections, including fungal infections, associated with T cell, neutrophil, and NK cell dysfunction. B cells may also show maturation abnormalities. Other features include autoimmune hemolytic anemia and abnormal platelet aggregation. The disease is caused by variants affecting the gene represented in this entry.

Domain organisation. The SH2 domain mediates interaction with phosphorylated CD6. The SH2 domain mediates interaction with SHB. Possesses an N-terminal acidic domain containing three tyrosine phosphorylation motifs, a central proline-rich region, and a C-terminal SH2 domain.
