Protein attributes

Sequence length	957 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Thought to be involved in the organization of the cytomatrix at the nerve terminals active zone (CAZ) which regulates neurotransmitter release. Seems to act together with BSN. May recruit liprin-alpha proteins to the CAZ.
Subunit structure	Interacts with BSN, ERC1, PPFIA1, PPFIA2, PPFIA3 and PPFIA4. Interacts through its C-terminus with the PDZ domain of RIMS1. Part of a complex consisting of ERC2, RIMS1 and UNC13A. Ref.4
Subcellular location	Cytoplasm. Cell junction › synapse. Cell junction › synapse › synaptosome. Cytoplasm › cytoskeleton. Note: In neurons, localized to synapses, and colocalizes with PCLO. Localized to the active zone of presynaptic density By similarity.
