    Summary
    Enables choline-phosphate cytidylyltransferase activity. Involved in CDP-choline pathway. Acts upstream of or within ovarian follicle development and spermatogenesis. Predicted to be located in endoplasmic reticulum. Is expressed in several structures, including alimentary system; genitourinary system; hemolymphoid system gland; nervous system; and sensory organ. Orthologous to human PCYT1B (phosphate cytidylyltransferase 1B, choline). [provided by Alliance of Genome Resources, Nov 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.
