CC -!- FUNCTION: A membrane-associated isoform may be involved in the
CC exocytosis of zymogens by pancreatic acini. May regulate calcium-
CC dependent activities in the endoplasmic reticulum lumen or post-ER
CC compartment. {ECO:0000269|PubMed:17442889}.
CC -!- SUBUNIT: A membrane-associated isoform interacts with STX3 and STXBP1.
CC {ECO:0000269|PubMed:17442889}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus lumen
CC {ECO:0000250|UniProtKB:Q61112}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Comment=Additional isoforms seem to exist.;
CC Name=1;
CC IsoId=Q91ZS3-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q91ZS3-2; Sequence=VSP_037452;
CC -!- TISSUE SPECIFICITY: A membrane-associated isoform is expressed in acini
CC of the pancreas (at protein level). Ubiquitous.
CC {ECO:0000269|PubMed:17442889, ECO:0000269|PubMed:18355758}.
CC -!- INDUCTION: Down-regulated by ethanol. Down-regulated during the
CC progression of cerebellum differentiation.
CC {ECO:0000269|PubMed:18355758}.
CC -!- DOMAIN: Binds calcium via its EF-hands. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the CREC family. {ECO:0000305}.
