Natl. Acad. Sci. U.S.A. 99:16899-16903(2002). CC -!- FUNCTION: Was first identified based on its probable role in the CC regulation of pituitary gene transcription. Binds to the prolactin CC gene (PRL) promoter and seems to activate transcription (By CC similarity). Guanine nucleotide exchange factor that activates CC SARA2. Required for the formation of COPII transport vesicles from CC the ER. CC -!- SUBUNIT: Binds SARA2. CC -!- SUBCELLULAR LOCATION: Nuclear. Membrane; single-pass membrane CC protein. Endoplasmic reticulum (By similarity). CC -!- TISSUE SPECIFICITY: Ubiquitous. CC -!- SIMILARITY: Contains 3 WD repeats.
