Summary: Enables small GTPase binding activity. A structural constituent of presynaptic active zone. Involved in regulation of calcium-dependent activation of synaptic vesicle fusion; regulation of presynaptic cytosolic calcium ion concentration; and synaptic vesicle priming. Acts upstream of or within retrograde transport, endosome to Golgi. Located in cytoplasm; podosome; and synapse. Is active in GABA-ergic synapse; glutamatergic synapse; and presynaptic cytosol. Is expressed in several structures, including genitourinary system; gut gland; oral epithelium; retina; and telencephalon. Orthologous to human ERC1 (ELKS/RAB6-interacting/CAST family member 1).

Several studies had established that ELKS is a redundant scaffold at the active zone, and that disruption of this scaffold impairs fusion of synaptic vesicles. In non-neuronal cells, scaffolding and exocytotic functions of ELKS seem to be important for constitutive secretion of other cargo. [review]

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.

Status: VALIDATED

Description

Transcript Variant: This variant (2) lacks several exons and its 3' terminal exon extends past a splice site that is used in variant 1. This results in a novel 3' coding region and 3' UTR, compared to variant 1. It encodes isoform 2 which is shorter and has a distinct C-terminus, compared to isoform 1.

Status: VALIDATED

Description

Transcript Variant: This variant (3) contains an alternate exon in the 3' region, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
