Function

Trafficking protein particle complex subunit 2 is thought to be part of a large multisubunit complex involved in the targeting and fusion of endoplasmic reticulum-to-Golgi transport vesicles with their acceptor compartment. In addition, the encoded protein can bind MBP1 and block its transcriptional repression capability.⁴

Genetic Location

The TRAPPC2 gene is located on the X-chromosome at position 22 between base-pairs 13,712,241 to 13,734,634.⁵

Clinical significance

Mutations in this gene are a cause of X-linked spondyloepiphyseal dysplasia tarda (SEDT).⁶

Interactions

TRAPPC2 has been shown to interact with Alpha-enolase⁷ and CLIC1.⁸
