Synonyms POB1; Partner of RalBP1; REPS2; RIP1; RLIP1; RLIP76; RalBP1-interacting protein 2
DTP Family Non ABC Multidrug Exporter (N-MDE) Family ;
Tissue Specificity Expressed at high levels in the cerebrum, cerebellum, lung, kidney, and testis. Weakly expressed in the kidney. Relatively highly expressed in androgen-dependent as compared to androgen-independent prostate cancer cell lines and xenografts. Isoform 2 is down-regulated during progression of prostate cancer.
