Function

[VASA1_DROME] Involved in translational control mechanisms operating in early stages of oogenesis. Required maternally in many stages of oogenesis, including cystocyte differentiation, oocyte differentiation, and specification of anterior-posterior polarity in the developing cysts. Essential for the formation and/or structural integrity of perinuclear nuage particles during germ cell formation. Required for gus, Fsn and aub accumulation at the posterior pole of the embryo. Required for the localization of vas to the perinuclear region of nurse cells.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8] ^[9] ^[10] ^[11]

Publication Abstract from PubMed

B30.2/SPRY domains are found in numerous proteins that cover a wide spectrum of biological functions, including regulation of cytokine signaling and innate retroviral restriction. Herein, we report the crystal structure of the B30.2/SPRY domain of a SPRY domain-containing SOCS box (SSB) protein, GUSTAVUS, complexed with a 20 amino acid peptide derived from the RNA helicase VASA, revealing how these domains recognize target proteins. The peptide-binding site is conformationally rigid and has a preformed pocket. The interaction between the pocket and the Asp-Ile-Asn-Asn-Asn-Asn sequence within the peptide accounts for the high-affinity binding between GUSTAVUS and VASA. This observation led to a facile identification of the Glu-Leu-Asn-Asn-Asn-Leu sequence as the recognition motif in a proapoptotic protein Par-4 for its interaction with a GUSTAVUS homolog, SSB-1. Ensuing analyses indicated that many B30.2/SPRY domains have a similar preformed pocket, which would allow them to bind multiple targets.
