Overview

RAB10 encodes a member of the Rab GTPase family involved in intracellular membrane trafficking. It plays critical roles in exocytic and endocytic pathways, including polarized membrane trafficking, autophagy, and lipid transport. RAB10 is essential for neuronal function, synaptic vesicle trafficking, dendrite morphogenesis, and myelin sheath formation.

The Rab GTPase family comprises over 60 members in humans, functioning as molecular switches that control vesicle transport between cellular compartments. RAB10 is particularly important for polarized trafficking in epithelial cells and [neurons](/entities/neurons), where it directs cargo to specific subcellular domains. Its functions in autophagy and lipid metabolism make it relevant to several neurodegenerative diseases.

Gene Structure

Genomic Organization

• Chromosome: 2
• Location: 2p22.3
• Exons: Multiple protein-coding exons spanning approximately 15 kb
• Transcript: Approximately 2.5 kb mRNA
• Promoter: Contains regulatory elements for ubiquitous expression

Splice Variants

• Multiple transcript variants identified
• Some variants show tissue-specific expression patterns

Protein Structure

RAB10 protein has the characteristic Rab GTPase fold:

• GTP-binding domain: Five conserved G motifs for nucleotide binding
• Switch I region: Conformational change upon GTP/GDP exchange
• Switch II region: Effector protein interaction site
• Hypervariable C-terminal region: Determines subcellular targeting
• C XC motif: Prenylation for membrane association
