Cell Biol. 216:1731-1743(2017). CC -!- FUNCTION: Guanine nucleotide exchange factor that specifically CC activates the small GTPase SAR1B. Mediates the recruitment of SAR1B and CC other COPII coat components to endoplasmic reticulum membranes and is CC therefore required for the formation of COPII transport vesicles from CC the ER. {ECO:0000250|UniProtKB:Q9WTV0, 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 gene CC (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 MIA2; recruits PREB to endoplasmic reticulum exit sites CC (PubMed:25202031, PubMed:27170179). {ECO:0000250|UniProtKB:Q9WUQ2, CC ECO:0000269|PubMed:25202031, ECO:0000269|PubMed:27170179}.

CC Note=Concentrates at endoplasmic reticulum exit sites (ERES), also CC known as transitional endoplasmic reticulum (tER). CC {ECO:0000269|PubMed:25202031, ECO:0000269|PubMed:28442536}.
