A novel primary human immunodeficiency due to deficiency in the WASP-interacting protein WIP

A female offspring of consanguineous parents, showed features of Wiskott-Aldrich syndrome (WAS), including recurrent infections, eczema, thrombocytopenia, defective T cell proliferation and chemotaxis, and impaired natural killer cell function. Cells from this patient had undetectable WAS protein (WASP), but normal WAS sequence and messenger RNA levels. WASP interacting protein (WIP), which sta...

WIP is a chaperone for Wiskott-Aldrich syndrome protein (WASP).

Wiskott-Aldrich syndrome protein (WASP) is in a complex with WASP-interacting protein (WIP). WASP levels, but not mRNA levels, were severely diminished in T cells from WIP(-/-) mice and were increased by introduction of WIP in these cells. The WASP binding domain of WIP was shown to protect WASP from degradation by calpain in vitro. Treatment with the proteasome inhibitors MG132 and bortezomib ...

WASP family proteins, more than Arp2/3 activators

Wiskott-Aldrich syndrome protein (WASP) family proteins have been extensively characterized as factors that promote the nucleation of actin through the activation of the protein complex Arp2/3. While yeast mostly have a single member of the family, mammalian cells have at least six different members, often with multiple isoforms. Members of the family are characterized by a common structure. Th...

Multiple WASP-interacting protein recognition motifs are required for a functional interaction with N-WASP.

The WASP-interacting protein (WIP) targets WASP/WAVE proteins through a constitutive interaction with an amino-terminal enabled/VASP homology (EVH1) domain. Parallel investigations had previously identified two distinct N-WASP binding motifs corresponding to WIP residues 451-461 and 461-485, and we determined the structure of a complex between WIP-(461-485) and the N-WASP EVH1 domain (Volkman, ...
