CC -!- FUNCTION: Transfers mannosyl residues to the hydroxyl group of serine
CC or threonine residues. Coexpression of both POMT1 and POMT2 is
CC necessary for enzyme activity, expression of either POMT1 or POMT2
CC alone is insufficient. {ECO:0000269|PubMed:20466645}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a dolichyl beta-D-mannosyl phosphate + L-seryl-[protein] = 3-
CC O-(alpha-D-mannosyl)-L-seryl-[protein] + a dolichyl phosphate + H(+);

CC Evidence={ECO:0000269|PubMed:20466645};
CC -!- PATHWAY: Protein modification; protein glycosylation.
CC {ECO:0000269|PubMed:20466645}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:Q9Y6A1}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- TISSUE SPECIFICITY: Widely expressed. Has particularly strong
CC expression in ovary, testis, liver, brain, muscle, heart and eye.
CC {ECO:0000269|PubMed:20466645}.
CC -!- DEVELOPMENTAL STAGE: Detected throughout development (PubMed:18632251,
CC PubMed:20466645). Highest expression levels are found at 0 hours post-
CC fertilization (hpf), probably due to perdurance of maternal transcripts
CC (PubMed:20466645). Expression levels remain high at 6 hpf and decrease
CC rapidly by 12 hpf, followed by a second moderate peak in expression at
CC 24 hpf (PubMed:20466645). Ubiquitously expressed during early stages of
CC development (PubMed:18632251, PubMed:20466645). At 16-24 hpf, mainly
CC found in eye, brain and somites (PubMed:18632251, PubMed:20466645). At
CC 30 hpf, has strongest expression in forebrain, cerebellum and hindbrain
CC (PubMed:18632251). {ECO:0000269|PubMed:18632251,
CC ECO:0000269|PubMed:20466645}.
CC -!- DISRUPTION PHENOTYPE: Morpholino knockdown of the protein results in
CC developmental delays at 18 hours post fertilization (hpf). At 48-72 hpf
CC the tail is abnormally twisted, and pericardium formation and eye
CC pigmentation are also abnormal. Swim bladders are incompletely formed.
CC Glycosylation of alpha-dystroglycan (dag1) is severely reduced.
CC {ECO:0000269|PubMed:20466645}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 39 family.
CC {ECO:0000305}.
