geneOn this page
Summary
TRAPPC6B (trafficking protein particle complex subunit 6B, HGNC:23066) is a protein-coding gene on chromosome 14q21.1, encoding Trafficking protein particle complex subunit 6B (Q86SZ2). Component of a transport protein particle (TRAPP) complex that may function in specific stages of inter-organelle traffic.
TRAPPC6B is a component of TRAPP complexes, which are tethering complexes involved in vesicle transport (Kummel et al., 2005 [PubMed 16025134]).

UniProt curated annotations — full annotation on UniProt →
Function. Component of a transport protein particle (TRAPP) complex that may function in specific stages of inter-organelle traffic. Specifically involved in the early development of neural circuitry, likely by controlling the frequency and amplitude of intracellular calcium transients implicated in the regulation of neuron differentiation and survival.
Subunit / interactions. Homodimer. Part of a TRAPP complex. Heterodimer with TRAPPC3. The heterodimer TRAPPC6B-TRAPPC3 interacts with TRAPPC1 likely providing a core for TRAPP complex formation.
Subcellular location. Golgi apparatus. cis-Golgi network. Endoplasmic reticulum.
Tissue specificity. Both isoforms are expressed ubiquitously (at transcript level), isoform 1 being the most predominant. Expressed in the fetal brain and different regions of the adult brain and spinal cord.
Disease relevance. Neurodevelopmental disorder with microcephaly, epilepsy, and brain atrophy (NEDMEBA) [MIM:617862] An autosomal recessive neurodevelopmental disorder characterized by microcephaly, global developmental delay, hypotonia, intellectual disability, autistic features such as poor social interaction, language impairment and repetitive automatism behaviors, and generalized tonic-clonic seizures. Brain imaging shows cortical atrophy, thin corpus callosum, and cerebellar and brainstem atrophy. The disease is caused by variants affecting the gene represented in this entry.
Similarity. Belongs to the TRAPP small subunits family. BET3 subfamily.
