Summary: Enables transmembrane transporter binding activity. Acts upstream of or within negative regulation of calcium ion transmembrane transport via high voltage-gated calcium channel and regulation of skeletal muscle contraction by calcium ion signaling. Located in I band and T-tubule. Is expressed in alimentary system and urinary system. Orthologous to human REM1 (RRAD and GEM like GTPase 1). [provided by Alliance of Genome Resources, Jan 2025]

We conclude that Rem is capable of regulating L-type current, that release of Rem block is modulated by cellular kinase pathways, and that the Ca(V)1.2 COOH terminus contributes to Rem-dependent channel inhibition.

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.
