Human Gene LCP2 (uc003man.1) Description and Page Index
  Description: Homo sapiens lymphocyte cytosolic protein 2 (SH2 domain containing leukocyte protein of 76kDa) (LCP2), mRNA.
RefSeq Summary (NM_005565): 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. [provided by RefSeq, Nov 2016]. Sequence Note: This RefSeq record was created from transcript and genomic sequence data to make the sequence consistent with the reference genome assembly. The genomic coordinates used for the transcript record were based on transcript alignments.

DESCRIPTION: RecName: Full=Lymphocyte cytosolic protein 2; AltName: Full=SH2 domain-containing leukocyte protein of 76 kDa; AltName: Full=SLP-76 tyrosine phosphoprotein; Short=SLP76;
FUNCTION: Involved in T-cell antigen receptor mediated signaling.
SUBUNIT: Interacts with SLA. Interacts with CBLB (By similarity). Interacts with the adapter proteins GRB2 and FYB. Interacts with SHB. Interacts with PRAM1.
INTERACTION: Q8IVH8:MAP4K3; NbExp=5; IntAct=EBI-346946, EBI-1758170; Q99JP0:Map4k3 (xeno); NbExp=2; IntAct=EBI-346946, EBI-5324222;
SUBCELLULAR LOCATION: Cytoplasm (Probable).
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.
DOMAIN: The SH2 domain mediates interaction with SHB.
PTM: 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.
SIMILARITY: Contains 1 SAM (sterile alpha motif) domain.
SIMILARITY: Contains 1 SH2 domain.

ModBase Predicted Comparative 3D Structure on Q13094
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
