Summary: Enables kinase activator activity. Acts upstream of or within positive regulation of MAPK cascade and protein localization to cell junction. Located in late endosome. Is expressed in several structures, including central nervous system; genitourinary system; and retina. Orthologous to human LAMTOR3 (late endosomal/lysosomal adaptor, MAPK and MTOR activator 3).

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.
