The protein encoded by this gene belongs to the synaptotagmin family. Synaptotagmins share a common domain structure that includes a transmembrane domain and a cytoplasmic region composed of 2 C2 domains, and are involved in calcium-dependent exocytosis of synaptic vesicles. This protein has been shown to be a key component of the secretory machinery involved in acrosomal exocytosis. Alternatively spliced transcript variants have been found for this gene.

Function:
May be involved in Ca(2+)-dependent exocytosis of secretory vesicles through Ca(2+) and phospholipid binding to the C2 domain or may serve as Ca(2+) sensors in the process of vesicular trafficking and exocytosis. May mediate Ca(2+)-regulation of exocytosis in acrosomal reaction in sperm (By similarity).
Subunit:
Homodimer (isoform 1). Isoform 1 forms heterodimers with SytIII, SytV and SytX. Interacts with STX1A, STX1B and STX2; the interaction is Ca(2+)-dependent. Isoform 2 is not able to form homodimer and heterodimers.
Subcellular Location:
Cytoplasmic vesicle, secretory vesicle, synaptic vesicle membrane; Single-pass membrane protein. Isoform 1: Membrane; Single-pass membrane protein. Note=Localized predominantly to endoplasmic reticulum (ER) and/or Golgi-like perinuclear compartment. Isoform 2: Cytoplasm, cytosol. Cell membrane; Peripheral membrane protein.
Similarity:
Belongs to the synaptotagmin family.
Contains 2 C2 domains.
