About This Section

Entrez Gene summary for CUL4B Gene:
This gene is a member of the cullin family. The encoded protein forms a complex that functions as an E3 ubiquitin
ligase and catalyzes the polyubiquitination of specific protein substrates in the cell. The protein interacts
with a ring finger protein, and is required for the proteolysis of several regulators of DNA replication
including chromatin licensing and DNA replication factor 1 and cyclin E. Multiple transcript variants encoding
different isoforms have been found for this gene. (provided by RefSeq, Jul 2008)

GeneCards Summary for CUL4B Gene: 
CUL4B (cullin 4B) is a protein-coding gene. Diseases associated with CUL4B include mental retardation, x-linked, syndromic 15, and mental retardation, x-linked, with short stature, small testes, muscle wasting, and tremor, and among its related super-pathways are Global Genomic NER (GG-NER) and Antigen processing: Ubiquitination & Proteasome degradation. GO annotations related to this gene include protein binding and ubiquitin protein ligase binding. An important paralog of this gene is CUL1.

UniProtKB/Swiss-Prot: CUL4B_HUMAN, Q13620
Function: Core component of multiple cullin-RING-based E3 ubiquitin-protein ligase complexes which mediate the
ubiquitination and subsequent proteasomal degradation of target proteins. The functional specificity of the E3
ubiquitin-protein ligase complex depends on the variable substrate recognition subunit. CUL4B may act within the
complex as a scaffold protein, contributing to catalysis through positioning of the substrate and the
ubiquitin-conjugating enzyme. Plays a role as part of the E3 ubiquitin-protein ligase complex in
polyubiquitination of CDT1, histone H2A, histone H3 and histone H4 in response to radiation-induced DNA damage.
Targeted to UV damaged chromatin by DDB2 and may be important for DNA repair and DNA replication. Required for
ubiquitination of cyclin E, and consequently, normal G1 cell cycle progression. Regulates the mammalian
target-of-rapamycin (mTOR) pathway involved in control of cell growth, size and metabolism. Specific CUL4B
regulation of the mTORC1-mediated pathway is dependent upon 26S proteasome function and requires interaction
between CUL4B and MLST8
