Cell 27:2008-2013(2016). CC -!- FUNCTION: Guanine nucleotide exchange factor that specifically CC activates the small GTPase SAR1B. Mediates the recruitement of CC SAR1B and other COPII coat components to endoplasmic reticulum CC membranes and is therefore required for the formation of COPII CC transport vesicles from the ER. {ECO:0000250|UniProtKB:Q9WTV0, CC ECO:0000250|UniProtKB:Q9WUQ2}. 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. CC {ECO:0000250|UniProtKB:Q9WTV0}. CC -!- SUBUNIT: Interacts with SAR1B (GDP-bound form) (By similarity). CC Interacts with CTAGE5; recruits PREB to endoplasmic reticulum exit CC sites (PubMed:25202031, PubMed:27170179). CC {ECO:0000250|UniProtKB:Q9WUQ2, ECO:0000269|PubMed:25202031, CC ECO:0000269|PubMed:27170179}.

Nucleus CC {ECO:0000250|UniProtKB:Q9WTV0}. Note=Concentrates at endoplasmic CC reticulum exit sites. {ECO:0000269|PubMed:25202031}. CC -!- TISSUE SPECIFICITY: Ubiquitous. {ECO:0000269|PubMed:10920239, CC ECO:0000269|PubMed:12735795}. CC -!- SIMILARITY: Contains 7 WD repeats. {ECO:0000255|PROSITE- CC ProRule:PRU00221}.
