TITLE Amphiphysin, a novel protein associated with synaptic vesicles JOURNAL EMBO J. 11 (7), 2521-2530 (1992) PUBMED 1628617 COMMENT REVIEWED REFSEQ: This record has been curated by NCBI staff. The reference sequence was derived from X81438.1 and AF034996.1. Summary: This gene encodes a protein associated with the cytoplasmic surface of synaptic vesicles. A subset of patients with stiff-man syndrome who were also affected by breast cancer are positive for autoantibodies against this protein. Alternate splicing of this gene results in two transcript variants encoding different isoforms. Additional splice variants have been described, but their full length sequences have not been determined. Transcript Variant: This variant (1) encodes the longer isoform.
