Summary: Contributes to dolichyl-phosphate-mannose-protein mannosyltransferase activity. Involved in several processes, including protein O-linked mannosylation; regulation of synaptic activity; and sarcomere organization. Located in endoplasmic reticulum. Part of dolichyl-phosphate-mannose-protein mannosyltransferase complex. Is expressed in several structures, including early stomodeal invagination; epithelium; germ band; gut section; and hindgut proper primordium. Used to study Walker-Warburg syndrome; congenital muscular dystrophy-dystroglycanopathy type A1; and muscular dystrophy-dystroglycanopathy. 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?

Protein tyrosine phosphatase 69D is a substrate of protein O-mannosyltransferases 1-2 that is required for the wiring of sensory axons in Drosophila.
Title: Protein tyrosine phosphatase 69D is a substrate of protein O-mannosyltransferases 1-2 that is required for the wiring of sensory axons in Drosophila.
POMTs were found to be required for proper axon connectivity of sensory neurons, suggesting that O-mannosylation regulates the sensory feedback controlling muscle contractions
Title: Protein O-Mannosyltransferases Affect Sensory Axon Wiring and Dynamic Chirality of Body Posture in the Drosophila Embryo.
Study demonstrated that expression of RNA interference (RNAi) for the rt gene and the tw mutant was almost completely lethal and semi-lethal, respectively.
Title: Increased apoptosis of myoblasts in Drosophila model for the Walker-Warburg syndrome.
the model that dPOMT1-dependent glycosylation of Dg is necessary for proper synaptic function and raise the possibility that similar synaptic defects occur in the congenital muscular dystrophies.
Title: Synaptic defects in a Drosophila model of congenital muscular dystrophy.
establish a central role for Dystroglycan (Dg) in maintaining integrity in Drosophila larval muscles and demonstrate the importance of glycosylation to Dg function in Drosophila
Title: Dystroglycan and protein O-mannosyltransferases 1 and 2 are required to maintain integrity of Drosophila larval muscles.
Drosophila POMT1 and POMT2 function as a protein O-mannosyltransferase in association with each other to generate and maintain normal muscle development.
Title: The twisted abdomen phenotype of Drosophila POMT1 and POMT2 mutants coincides with their heterophilic protein O-mannosyltransferase activity.
