Solute carrier family 35 member D1 (SLC35D1)

Target
SLC35D1
Molecular classification
Transporter, Solute carrier (SLC) family member, Nucleotide sugar transporter
01

Overview

Solute carrier family 35 member D1 (SLC35D1) is a nucleotide sugar transporter located in the endoplasmic reticulum membrane, functioning as an antiporter that exchanges nucleotide sugars such as UDP-glucuronic acid (UDP-GlcA) and UDP-N-acetylgalactosamine (UDP-GalNAc) from the cytosol into the ER lumen, where they are used as substrates for glycosylation reactions. This transporter is critical for biosynthetic pathways including glucuronidation and chondroitin sulfate biosynthesis, which are essential for proper extracellular matrix formation and skeletal development. Mutations in SLC35D1 are associated with severe skeletal dysplasias, particularly Schneckenbecken dysplasia, highlighting its crucial developmental role.

Other names

02

Mechanism of action

Antiporter function: transports UDP-sugars into ER lumen in exchange for cognate nucleoside monophosphate or another nucleotide sugar

03

Biological functions

Nucleotide sugar transport (especially UDP-glucuronic acid and UDP-N-acetylgalactosamine)Glycosylation (specifically glycosylation of glycoconjugates in ER and Golgi)GlucuronidationChondroitin sulfate biosynthesisExtracellular matrix formation and normal skeletal development
04

Disease associations

Skeletal dysplasia (notably Schneckenbecken dysplasia)Acromesomelic dysplasia 2AOther disorders involving glycosylation defects
05

Safety considerations

No direct pharmacological safety concerns reported; gene mutations cause severe congenital skeletal disorders indicating essential role in development
06

Interacting drugs

No specific drugs directly targeting SLC35D1 are reported in the cited databases or literature. Its dysfunction is linked to congenital disorders rather than being a current pharmacological target.
07

Biomarkers

Mutations in SLC35D1 gene serve as biomarkers for Schneckenbecken dysplasia and related congenital skeletal disorders
