CRBN, also known as mental retardation, non-syndromic, autosomal recessive, 2A, is a substrate receptor of the CRL4CRBN E3 ubiquitin ligase complex and is widely expressed in various tissues, particularly abundant in the nervous system. As the substrate recognition subunit, CRBN forms an E3 ubiquitin ligase complex with DDB1, Cul4A, and ROC1, promoting the ubiquitination and subsequent proteasomal degradation of target proteins such as MEIS2 or ILF2. CRBN maintains synaptic glutamate release, which is crucial for cognitive functions like memory and learning, and may influence anxiety-like behavior by modulating BK channels. CRBN also plays a negative regulatory role in the TLR4 signaling pathway by interacting with TRAF6 and ECSIT, inhibiting the ubiquitination of ECSIT. Abnormal function of CRBN is associated with multiple diseases, including intellectual developmental disorders and certain cancers, and it serves as a target for immunomodulatory drugs such as thalidomide, lenalidomide, and busulfan.

IHC image of CSB-PA842761ESR1HU diluted at 1:100 and staining in paraffin-embedded human testis tissueperformed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.
