Summary: Enables identical protein binding activity and protein kinase binding activity. Involved in regulation of synaptic vesicle cycle and synaptic vesicle cycle. Acts upstream of or within neurotransmitter secretion. Located in several cellular components, including postsynaptic density; synaptic vesicle membrane; and synaptonemal complex. Is active in several cellular components, including Schaffer collateral - CA1 synapse; cell body; and dendrite. Is expressed in several structures, including intercostal muscle; molar; nervous system; oocyte; and sensory organ. Used to study autism spectrum disorder and epilepsy.

Orthologous to human SYN1 (synapsin I). [provided by Alliance of Genome Resources, Oct 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
