Summary: Enables protein domain specific binding activity. Involved in several processes, including cellular response to thyroid hormone stimulus; positive regulation of G1/S transition of mitotic cell cycle; and regulation of postsynaptic neurotransmitter receptor diffusion trapping. Acts upstream of or within apical protein localization and microvillus assembly. Located in several cellular components, including lamellipodium; ruffle; and stereocilium base. Colocalizes with plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; hemolymphoid system; and sensory organ. Used to study Dubin-Johnson syndrome. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 24. Orthologous to human RDX (radixin).

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.
