The ISPD Polyclonal Antibody (PAC046454) is a valuable tool for researchers studying ISPD, an essential enzyme involved in the biosynthesis of CDP-ribitol, a precursor required for protein glycosylation. This antibody, produced in rabbits, exhibits high reactivity with human samples and is validated for Western blot applications. By binding specifically to the ISPD protein, this antibody enables reliable detection and analysis in various cell types, making it ideal for investigations in glycobiology and genetic disorders.
ISPD plays a crucial role in protein glycosylation, a fundamental process that impacts protein function and cell signaling. Dysregulation of this pathway has been linked to developmental disorders, neurodegenerative diseases, and congenital disorders, highlighting the importance of studying ISPD in biological processes. Understanding the mechanisms underlying ISPD function is essential for advancing research in these areas and may lead to the development of targeted therapies for related conditions.

Background:
Required for protein O-linked mannosylation. Probably acts as a nucleotidyltransferase involved in synthesis of a nucleotide sugar. Required for dystroglycan O-mannosylation.
ISPD: Required for protein O-linked mannosylation. Probably acts as a nucleotidyltransferase involved in synthesis of a nucleotide sugar. Required for dystroglycan O-mannosylation. Defects in ISPD are the cause of muscular dystrophy- dystroglycanopathy congenital with brain and eye anomalies type A7 (MDDGA7). MDDGA7 is an autosomal recessive disorder characterized by congenital muscular dystrophy associated with cobblestone lissencephaly and other brain anomalies, eye malformations, profound mental retardation, and death usually in the first years of life. Included diseases are the more severe Walker-Warburg syndrome and the slightly less severe muscle-eye- brain disease. Belongs to the IspD family. 2 isoforms of the human protein are produced by alternative splicing.Protein type: EC 2.7.7.-; TransferaseChromosomal Location of Human Ortholog: 7p21.2Molecular Function: nucleotidyltransferase activityBiological Process: axon guidance; isoprenoid biosynthetic process; protein amino acid O-linked mannosylationDisease: Muscular Dystrophy-dystroglycanopathy (congenital With Brain And Eye Anomalies), Type A, 7; Muscular Dystrophy-dystroglycanopathy (limb-girdle), Type C, 7

NCBI Summary:
This gene encodes a 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase-like protein. Mutations in this gene are the cause of Walker-Warburg syndrome. Alternate splicing results in multiple transcript variants. [provided by RefSeq, May 2012]
