Protein names

Wiskott-Aldrich syndrome protein , WASp

Protein function

Effector protein for Rho-type GTPases. Regulates actin filament reorganization via its interaction with the Arp2/3 complex. Important for efficient actin polymerization. Possible regulator of lymphocyte and platelet function. Mediates actin filament reorganization and the formation of actin pedestals upon infection by pathogenic bacteria.

Protein tissue specificity

Expressed predominantly in the thymus. Also found, to a much lesser extent, in the spleen.

Involvement in disease

Wiskott-Aldrich syndrome (WAS) [MIM:301000]: An X-linked recessive immunodeficiency characterized by eczema, thrombocytopenia, recurrent infections, and bloody diarrhea. Death usually occurs before age 10. . Note: The disease is caused by mutations affecting the gene represented in this entry.; Thrombocytopenia 1 (THC1) [MIM:313900]: Thrombocytopenia is defined by a decrease in the number of platelets in circulating blood, resulting in the potential for increased bleeding and decreased ability for clotting. . Note: The disease is caused by mutations affecting the gene represented in this entry.; Neutropenia, severe congenital, X-linked (XLN) [MIM:300299]: A disorder of hematopoiesis characterized by maturation arrest of granulopoiesis at the level of promyelocytes with peripheral blood absolute neutrophil counts below 0.5 x 10(9)/l and early onset of severe bacterial infections. . Note: The disease is caused by mutations affecting the gene represented in this entry.

Protein sequence and domain

The WH1 (Wasp homology 1) domain may bind a Pro-rich ligand. / The CRIB (Cdc42/Rac-interactive-binding) region binds to the C-terminal WH2 domain in the autoinhibited state of the protein. Binding of Rho-type GTPases to the CRIB induces a conformation change and leads to activation. / Contains 1 CRIB domain. / Contains 1 WH1 domain. / Contains 1 WH2 domain.

Protein post-translational modifications

Phosphorylated at Tyr-291 by FYN and HCK, inducing WAS effector activity after TCR engagement. Phosphorylation at Tyr-291 enhances WAS activity in promoting actin polymerization and filopodia formation.
