Activity summary

SLP76 also known as Src homology 2 domain-containing leukocyte phosphoprotein of 76 kDa plays a pivotal role in intracellular signaling. This adaptor protein weighs approximately 76 kilodaltons and is predominantly expressed in hematopoietic cells particularly T cells NK cells mast cells and platelets. SLP76 functions to relay signals from the cell surface to the nucleus affecting cellular responses including activation proliferation and differentiation.

Biological function summary

This adaptor protein serves as a scaffold linking membrane-proximal signaling to downstream cellular effectors. SLP76 forms part of a larger signaling complex with proteins such as LAT (Linker for Activation of T cells) and Gads facilitating the assembly of multi-protein complexes necessary for signal transduction. It coordinates the recruitment and activation of several enzymes and substrates which leads to robust immune cell responses.

Pathways

The function of SLP76 integrates into T cell receptor (TCR) signaling and integrin signaling pathways. In TCR signaling SLP76 interacts closely with proteins LAT and ZAP-70 which are triggered upon antigen recognition. This interaction propagates the immune response by activating downstream effectors like MAP kinases and NF-kB. In integrin signaling SLP76 helps mediate cytoskeletal rearrangements which are important for cell migration and adhesion.

Associated diseases and disorders

Mutations or dysregulation of SLP76 associate with immunodeficiencies and hematologic malignancies. Aberrant SLP76 activity can lead to inappropriate activation or inactivation of immune responses contributing to disorders as SCID (Severe Combined Immunodeficiency) and some types of leukemia. Additionally it connects with proteins such as LAT in disease contexts reflecting a shared pathway disruption contributing to the pathophysiology of these conditions.
