Summary: Enables several functions, including identical protein binding activity; nitric-oxide synthase inhibitor activity; and scaffold protein binding activity. Involved in positive regulation of insulin secretion involved in cellular response to glucose stimulus and spermatid development. Acts upstream of or within negative regulation of nitric oxide biosynthetic process. Located in axon cytoplasm and secretory granule. Part of cytoplasmic dynein complex. Used to study hypertension and impotence. Biomarker of cardiac arrest; congestive heart failure; and middle cerebral artery infarction. Orthologous to human DYNLL1 (dynein light chain LC8-type 1).

It has been found that APC2 localizes as distinct clusters along microtubule bundles in dendrites, and that this localization is driven by LC8-binding and two separate microtubule-interacting domains.

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.
