Protein

Proline-serine-threonine phosphatase-interacting protein 1

Gene

Pstpip1

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Involved in regulation of the actin cytoskeleton. May regulate WAS actin-bundling activity. Bridges the interaction between ABL1 and PTPN18 leading to ABL1 dephosphorylation. May play a role as a scaffold protein between PTPN12 and WAS and allow PTPN12 to dephosphorylate WAS. Has the potential to physically couple CD2 and CD2AP to WAS. Acts downstream of CD2 and CD2AP to recruit WAS to the T-cell:APC contact site so as to promote the actin polymerization required for synapse induction during T-cell activation. Down-regulates CD2-stimulated adhesion through the coupling of PTPN12 to CD2. Also has a role in innate immunity and the inflammatory response. Recruited to inflammasomes by MEFV. Induces formation of pyroptosomes, large supramolecular structures composed of oligomerized PYCARD dimers which form prior to inflammatory apoptosis. Binding to MEFV allows MEFV to bind to PYCARD and facilitates pyroptosome formation. Regulates endocytosis and cell migration in neutrophils.5 Publications

Subcellular locationi

Cytoplasm. Cytoplasmcytoskeleton. Cell projectionlamellipodium. Cell projectionuropodium By similarity. Cytoplasmperinuclear region. Cleavage furrow
Note: During interphase, colocalizes with F-actin in the cortical cytoskeleton, lamellipodia, and stress fibers. In dividing cells, colocalizes with the F-actin rich cytokinetic cleavage furrow. Colocalized with WAS to filamentous structures within the cytoplasm. Colocalized with PTPN12 in the cytoplasm and the perinuclear region. Colocalized with CD2AP and WAS in the actin cytoskeleton. Colocalized with CD2, CD2AP and WAS at the site of T-cell:APC contact. In monocytes, forms a branched filamentous network in the cytoplasm (By similarity). In migrating neutrophils, localizes most strongly to the trailing edge of the uropod where it colocalizes with PIP5K1C (By similarity). In transfected cells, forms relatively straight filaments radiating out from the nucleus (By similarity). Colocalizes with MEFV, particularly at the branch point of filaments (By similarity). Filament formation requires an intact tubulin cytoskeleton (By similarity).By similarity

Post-translational modificationi

Dephosphorylated on Tyr-344 by PTPN18, this event negatively regulates the association of PSTPIP1 with SH2 domain-containing proteins as tyrosine kinase. Phosphorylation of Tyr-344 is probably required for subsequent phosphorylation at other tyrosine residues. Phosphorylation is induced by activation of the EGFR and PDGFR in a ABL1 dependent manner. The phosphorylation regulates the interaction with WAS and with MEFV.4 Publications
