E3 ubiquitin-protein ligase. Defects in TRIM37 are the cause of mulibrey nanism (MUL); also known as muscle-liver-brain-eye nanism. MUL is an autosomal recessive disorder that involves several tissues of mesodermal origin, implying a defect in a highly pleiotropic gene. Characteristic features include severe growth failure of prenatal onset and constrictive pericardium with consequent hepatomegaly. In addition, muscle hypotonia, J-shaped sella turcica, yellowish dots in the ocular fundi, typical dysmorphic features and hypoplasia of various endocrine glands causing hormonal deficiency are common. Belongs to the TRIM/RBCC family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Molecular Function: protein binding; protein homodimerization activity; tumor necrosis factor receptor binding; ubiquitin protein ligase binding; ubiquitin-protein ligase activity
Biological Process: activation of NF-kappaB transcription factor; inhibition of NF-kappaB transcription factor; negative regulation of centriole replication; negative regulation of transcription from RNA polymerase II promoter; positive regulation of transcription factor activity; protein autoubiquitination
