Summary
Enables choline-phosphate cytidylyltransferase activity. Involved in several processes, including determination of adult lifespan; establishment of ommatidial planar polarity; and imaginal disc-derived wing morphogenesis. Located in nucleus. Is expressed in several structures, including adult head; amnioserosa primordium; anterior endoderm; embryonic/larval midgut primordium; and epithelium. Human ortholog(s) of this gene implicated in congenital generalized lipodystrophy and spondylometaphyseal dysplasia with cone-rod dystrophy. Orthologous to human PCYT1A (phosphate cytidylyltransferase 1A, choline). [provided by Alliance of Genome Resources, Nov 2024]
