Description at least 21 exons. 500 Kb
Transcription 9.0 Kb and other smaller mRNAs ; alternative splicing: at least 5 isoforms (a, b, g, d, e)


Description a : 948 amino acids, b: 992 amino acids, g: 720 amino acids, d:1088 amino acids, e:1116 amino acids, containing eight to ten coiled-coil domains.
Rich in glutamic acid (E), leucine (L), lysine (K) and serine (S).
Mouse homolog of ELKS a subtype binds to RIM (Rab3-interacting molecule) which is presynaptic active zone protein and regulates neurotransmitter release.
Mouse homologs of ELKS bind to rab6 which regulate intracellular transport.
Expression Ubiquitous, a and b are abundant in the brain. d and e predominate in the testis, thyroid and other tissues.
Function unknown
Homology CAST or ERC2
