DDB1 (damage-specific DNA binding protein 1) and CRBN (cereblon) contribute importantly to the functionality of this complex. DDB1 protein weighs about 127 kDa. CRBN is an important component with a mass of about 51 kDa. This complex is highly expressed in various human tissues including the brain liver and lungs. The complex serves as an E3 ubiquitin ligase controlling protein homeostasis.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThe DDB1 CRBN and associated proteins interact closely in the ubiquitin-proteasome system functioning as a part of the larger cullin-RING ligase complex. It acts by recognizing and binding target proteins tagging them for degradation which mediates cellular processes such as DNA repair cell cycle and apoptosis. DDB1 acts as an adaptor that recruits substrate-specific receptors and CRBN often serves as a specificity factor within the protein assembly.\u003cbr\u003e\nPathways\u003cbr\u003e\nThe DDB1-CRBN complex intricately integrates into the ubiquitin-proteasome pathway and the cell cycle regulation pathway. It is important for the removal of misfolded or damaged proteins preventing protein aggregation. It interacts with proteins such as c-JUN and MDM2 which link it to cell cycle regulation and stress response pathways. This complex functions in substrate recognition and subsequent degradation to maintain cellular equilibrium.\u003cbr\u003e\nThe dysfunction or deregulation of the DDB1-CUL4A-RBX1-CRBN system associates with cancers and certain neurodegenerative diseases. In hematological malignancies improper CRBN function affects protein homeostasis contributing to disease progression. CRBN is also implicated in certain forms of cognitive dysfunctions where its disrupted function affects neurological signaling pathways. Therapeutic strategies often target this complex indirectly highlighting its potential role in disease treatment alongside proteins like p53 and Cyclin E.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843995193513,"sku":"ab271467","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab271467","provider":"Iright","version":"1.0","type":"link"}
