Disease
PPIP1_HUMAN Defects in PSTPIP1 are the cause of PAPA syndrome (PAPAS) [MIM:604416; also known as pyogenic sterile arthritis, pyoderma gangrenosum and acne or familial recurrent arthritis (FRA). PAPAS is characterized by autosomal dominant inheritance of early onset, primarily affecting skin and joint tissues. Recurring inflammatory episodes lead to accumulation of sterile, pyogenic, neutrophil-rich material within the affected joints, ultimately resulting in significant destruction.[1] [2]
Function
PPIP1_HUMAN Involved in regulation of the actin cytoskeleton. May regulate the WAS actin-bundling activity. Bridges the interaction between ABL1 and PTPN18 leading to the ABL1 dephosphorylation. May play a role as a scaffold protein between PTPN12 and WAS and allows 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 (By similarity). Down-regulates CD2-stimulated adhesion through the coupling of PTPN12 to CD2.[3]
