Recombinant Human Probable E3 ubiquitin-protein ligase HERC4 (HERC4), Truncated

Uniprot Id

Q5GLZ8

Target Species

Human

Target Name

HERC4

Target Full Name

Probable E3 ubiquitin-protein ligase HERC4

Target Function

Probable E3 ubiquitin-protein ligase involved in either protein trafficking or in the distribution of cellular structures. Required for spermatozoon maturation and fertility, and for the removal of the cytoplasmic droplet of the spermatozoon. E3 ubiquitin-protein ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfer it to targeted substrates.

Target Subcellular Location

Cytoplasm, cytosol. Note=shows a punctate cytoplasmic distribution.

Target Tissue Specificity

Expressed in brain and testis and detected in heart and placenta.

Target Synonyms

DKFZP564G092; HECT and RLD domain containing E3 ubiquitin protein ligase 4; HECT domain and RCC1 like domain containing protein 4; HECT domain and RCC1-like domain-containing protein 4; Hect domain and RLD 4; HERC 4; HERC4; HERC4_HUMAN; KIAA1593; Probable E3 ubiquitin protein ligase HERC4; Probable E3 ubiquitin-protein ligase HERC4

Target Background

HERC4 belongs to the HERC family of ubiquitin ligases, all of which contain a HECT domain and at least 1 RCC1 (MIM 179710)-like domain (RLD). The 350-amino acid HECT domain is predicted to catalyze the formation of a thioester with ubiquitin before transferring it to a substrate, and the RLD is predicted to act as a guanine nucleotide exchange factor for small G proteins (Hochrainer et al., 2005 [PubMed 15676274]).
