These hect domain and RLD 4 ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. hect domain and RLD 4 is an alias of the human HERC4 gene, which encodes the protein, HECT and RLD domain containing E3 ubiquitin protein ligase 4. Notably, hect domain and RLD 4 is known to play a role in cell differentiation and protein ubiquitination, among other functions. The HERC4 protein is 1057 amino acid residues in length and 118.6 kilodaltons in mass. However, as many as 6 protein isoforms have been identified. It is localized to the cytoplasm of the cell. In terms of tissue specificity, it is reported to be expressed in the brain and testis and detected in heart and placenta. Other names for this target antigen include probable E3 ubiquitin-protein ligase HERC4, HECT domain, and RCC1-like domain-containing protein 4, and HECT-type E3 ubiquitin transferase HERC4.
