RC STRAIN=Hereford; TISSUE=Fetal skin;
RG NIH - Mammalian Gene Collection (MGC) project;
RL Submitted (FEB-2007) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Involved in both the retinal photoreceptor ribbon synapse
CC formation and physiological functions of visual perception. Necessary
CC for proper bipolar dendritic tip apposition to the photoreceptor ribbon
CC synapse. Promotes matrix assembly and cell adhesiveness (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Interacts with DAG1 alpha-dystroglycan. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular
CC matrix {ECO:0000250|UniProtKB:Q4VBE4}. Synaptic cleft
CC {ECO:0000250|UniProtKB:Q4VBE4}. Presynaptic active zone
CC {ECO:0000250|UniProtKB:Q4VBE4}. Note=Detected in the synaptic cleft of
CC the ribbon synapse around the postsynaptic terminals of bipolar cells.
CC Colocalizes with BSN, CTBP2 and DAG1 in photoreceptor synaptic
CC terminals. {ECO:0000250|UniProtKB:Q4VBE4}.
CC -!- PTM: O-glycosylated; contains chondroitin sulfate and heparan sulfate.
CC {ECO:0000250}.
