    Avi-tag Biotinylated

    E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

靶点详情

  • 功能：
    Catalyzes the transfer of CDP-ribitol to ribitol 5-phosphate previously attached by FKTN/fukutin of to the phosphorylated O-mannosyl trisaccharide (N-acetylgalactosamine-beta-3-N-acetylglucosamine-beta-4-(phosphate-6-)mannose), a carbohydrate structure present in alpha-dystroglycan (DAG1). This constitutes the second step in the formation of the ribose 5-phosphate tandem repeat which links the phosphorylated O-mannosyl trisaccharide to the ligand binding moiety composed of repeats of 3-xylosyl-alpha-1,3-glucuronic acid-beta-1.

    1. The FKRP-related disorders should be included as a differential diagnosis in Mexican patients with neuromuscular disorders and normal results on DMD gene deletion/duplication analysis. This and previous reports, along with data from the main genotype databases, collectively suggest that in Mexico the FKRP-related disorders are due to the p.(Asn463Asp) and the common European p.(Leu276Ile) pathogenic variants. PMID: 29065428
    2. The results suggest that fukutin and FKRP not only participate in the synthesis of O-mannosyl glycans added to alpha-dystroglycan in the endoplasmic reticulum and Golgi complex, but that they could also play a role, that remains to be established, in the nucleus of retinal neurons. PMID: 29416295

    5. Fukutin, FKRP, and TMEM5 form a complex while maintaining each of their enzyme activities. Data showed that endogenous fukutin and FKRP enzyme activities coexist with TMEM5 enzyme activity, and suggest the possibility that formation of this enzyme complex may contribute to specific and prompt biosynthesis of glycans that are required for dystroglycan function. PMID: 29477842
