Summary: Enables cAMP response element binding protein binding activity and protein C-terminal S-isoprenylcysteine carboxyl O-methyltransferase activity. Involved in CAAX-box protein maturation. Acts upstream of or within several processes, including C-terminal protein methylation; TOR signaling; and determination of adult lifespan. Predicted to be active in endoplasmic reticulum membrane. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Orthologous to human ICMT (isoprenylcysteine carboxyl methyltransferase). [provided by Alliance of Genome Resources, Dec 2024]

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.

Status: VALIDATED

Description

Transcript Variant: This variant (2) contains an alternate internal exon, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
