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}.
