Summary: Predicted to enable mannosyltransferase activity. Acts upstream of or within extracellular matrix organization. Located in acrosomal vesicle and sarcoplasmic reticulum. Part of dolichyl-phosphate-mannose-protein mannosyltransferase complex. Is expressed in several structures, including central nervous system; eye; germ cell of gonad; heart; and hemolymphoid system gland. Used to study muscular dystrophy-dystroglycanopathy type B1. Human ortholog(s) of this gene implicated in cardiomyopathy; cleft lip; lissencephaly; and muscular dystrophy (multiple). Orthologous to human POMT1 (protein O-mannosyltransferase 1).

What's a GeneRIF?

-mannosylation of alpha-DG in the retina carried out by POMT1 is crucial for the establishment of proper synapses at the OPL and transmission of visual information from cones and rods to their postsynaptic neurons.
Title: Impairment of photoreceptor ribbon synapses in a novel Pomt1 conditional knockout mouse model of dystroglycanopathy.
during embryogenesis, Pomt1 is expressed in the neural tube, the developing eye, and the mesenchyme; targeted deletion of Pomt1 results in early embryonic lethality due to defects in the assembly of Reichert's membrane
Title: Targeted disruption of the Walker-Warburg syndrome gene Pomt1 in mouse results in embryonic lethality.

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.
