Summary
Enables enzyme regulator activity. Involved in epithelial fluid transport. Acts upstream of or within several processes, including protein export from nucleus; regulation of mRNA 3'-end processing; and regulation of monoatomic ion transport. Located in cytosol and intracellular membrane-bounded organelle. Is expressed in several structures, including alimentary system; integumental system; nervous system; respiratory system; and sensory organ. Orthologous to human AHCYL1 (adenosylhomocysteinase like 1). [provided by Alliance of Genome Resources, Apr 2025]

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.
