    Summary
    Predicted to enable phosphatidylinositol N-acetylglucosaminyltransferase activity. Acts upstream of or within GPI anchor biosynthetic process and cellular response to leukemia inhibitory factor. Predicted to be located in endoplasmic reticulum membrane. Predicted to be part of glycosylphosphatidylinositol-N-acetylglucosaminyltransferase (GPI-GnT) complex. Is expressed in 1st branchial arch; central nervous system; heart; limb; and medial-nasal process. Used to study autosomal recessive congenital ichthyosis 4B. Human ortholog(s) of this gene implicated in multiple congenital anomalies-hypotonia-seizures syndrome 2 and paroxysmal nocturnal hemoglobinuria. Orthologous to human PIGA (phosphatidylinositol glycan anchor biosynthesis class A). [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.
