Rabbit Anti-SIT/FITC Conjugated antibody
background:
The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP contains two tandem Src homology-2 domains, which function as phospho-tyrosine binding domains and mediate the interaction of this PTP with its substrates. This PTP is widely expressed in most tissues and plays a regulatory role in various cell signaling events that are important for a diversity of cell functions, such as mitogenic activation, metabolic control, transcription regulation, and cell migration. Mutations in this gene are a cause of Noonan syndrome as well as acute myeloid leukemia. Two transcript variants encoding different isoforms have been found for this gene.

Function:
Negatively regulates TCR (T-cell antigen receptor)-mediated signaling in T-cells. Involved in positive selection of T-cells.
Subcellular Location:
Cell membrane.
Tissue Specificity:
Specifically expressed in T- and B-cells. Present in plasma cells but not in germinal center B-cells (at protein level). Expressed in T- and B-cell lymphoma.
Post-translational modifications:
Phosphorylated on tyrosines by LCK, FYN or ZAP70 upon TCR activation; which leads to the recruitment of PTPN11, GRB2 and CSK.
