Previous GeneCards Identifiers for UBE4A Gene
This gene encodes a member of the U-box ubiquitin ligase family. The encoded protein is involved in multiubiquitin chain assembly and plays a critical role in chromosome condensation and separation through the polyubiquitination of securin. Autoantibodies against the encoded protein may be markers for scleroderma and Crohn's disease. A pseudogene of this gene is located on the long arm of chromosome 3. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Feb 2011]
GeneCards Summary for UBE4A Gene

Among its related pathways are Immune System and Antigen processing- Ubiquitination and Proteasome degradation. GO annotations related to this gene include ligase activity and ubiquitin-ubiquitin ligase activity. An important paralog of this gene is UBE4B.
UniProtKB/Swiss-Prot for UBE4A Gene
Ubiquitin-protein ligase that probably functions as an E3 ligase in conjunction with specific E1 and E2 ligases. May also function as an E4 ligase mediating the assembly of polyubiquitin chains on substrates ubiquitinated by another E3 ubiquitin ligase. Mediates Lys-48-linked polyubiquitination of substrates.
