Gene: CRPPA (CDP-L-ribitol pyrophosphorylase A) Homo sapiens
Symbol: CRPPA
Name: CDP-L-ribitol pyrophosphorylase A
Description: Exhibits D-ribitol-5-phosphate cytidylyltransferase activity and protein homodimerization activity. Involved in protein O-linked mannosylation. Localizes to the cytosol. Implicated in autosomal recessive limb-girdle muscular dystrophy type 2U and congenital muscular dystrophy-dystroglycanopathy A7.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase-like protein; 4-diphosphocytidyl-2C-methyl-D-erythritol synthase homolog; D-ribitol-5-phosphate cytidylyltransferase; FLJ42815; hCG_1745121; hISPD; isoprenoid synthase domain containing; isoprenoid synthase domain-containing protein; ISPD; LGMDR20; MDDGA7; MDDGC7; Nip; notch1-induced protein; RP11-196O16.1; testicular tissue protein Li 97
