Structure of the BTB (Tramtrack and Bric a brac) domain of human Gigaxonin

Disease

[GAN_HUMAN] Defects in GAN are the cause of giant axonal neuropathy (GAN) [MIM:256850]. GAN is a severe autosomal recessive sensorimotor neuropathy affecting both the peripheral nerves and the central nervous system. It is characterized by neurofilament accumulation, leading to segmental distention of axons.[1][2][3][4][5][6]

Function

[GAN_HUMAN] Probable cytoskeletal component that directly or indirectly plays an important role in neurofilament architecture. Substrate-specific adapter of an E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Controls degradation of TBCB. Controls degradation of MAP1B and MAP1S, and is critical for neuronal maintenance and survival.[7][8][9][10][11]

About this Structure

2ppi is a 1 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA.
