Background

Gene Function. Salcini et al. (1997) reported that both the RAB and RABR (604018) proteins bind to the EH protein-protein interaction domain found in EPS15 (600051) and other proteins. Coimmunoprecipitation studies demonstrated that RAB and EPS15 are associated in vivo.

Bogerd et al. (1995) showed that RAB binds to the Rev activation domain in vitro and in vivo and also to functionally equivalent domains in Rex and in other Rev proteins from diverse viruses.

By ablating RIP activity with a dominant-negative mutant or RNA interference, Sanchez-Velar et al. (2004) analyzed the role of RIP in Rev-directed RNA movement by RNA in situ hybridization. In the absence of functional RIP, Rev-directed RNAs mislocalized and aberrantly accumulated at the nuclear periphery, where RIP is localized. In contrast, in the absence of Rev or a Rev cofactor, Rev-directed RNAs remained nuclear. The RNA mislocalization pattern was specific to viral RNA. The intracellular distribution patterns of cellular mRNA, nuclear proteins, and cellular proteins containing a nuclear export signal were unaffected. Sanchez-Velar et al. (2004) concluded that RIP is a cellular Rev cofactor essential for the nuclear export of viral RNAs. Animal Model. Kang-Decker et al. (2001) generated mice deficient in HRB by targeted disruption. Male mice with a null mutation in Hrb were infertile and displayed round-headed spermatozoa that lacked an acrosome. In wildtype spermatids, Hrb was associated with the cytosolic surface of proacrosomic transport vesicles that fuse to create a single large acrosomic vesicle at step 3 of spermiogenesis. Although proacrosomic vesicles form in spermatids that lack Hrb, the vesicles are unable to fuse, blocking acrosome development at step 2. Kang-Decker et al. (2001) concluded that HRB is required for docking and/or fusion of proacrosomic vesicles during acrosome biogenesis.
