Supplementary information

RBX1 also known as RING-box protein 1 or ROC1 acts as an E3 ubiquitin ligase part of the ubiquitin-proteasome system. This protein facilitates the transfer of ubiquitin from E2 enzymes to target substrates marking them for degradation. The molecular weight of RBX1 is approximately 12 kDa. RBX1 is mainly expressed in various human tissues with significant expression in the heart brain and skeletal muscle. Its expression in these tissues suggests a wide involvement in cellular processes.
Biological function summary

RBX1 associates with the cullin-RING ubiquitin ligase (CRL) complex. It interacts with cullin proteins and other regulatory subunits to promote the polyubiquitination and subsequent degradation of target proteins. This regulatory activity influences many cellular processes including cell cycle progression DNA repair and signal transduction. By ensuring the degradation of proteins at the right time RBX1 maintains cellular homeostasis.

Pathways

RBX1 plays an important role in the control of protein stability through the ubiquitin-proteasome pathway. This pathway is important for regulating key cellular functions like the entrainment of the cell cycle and apoptosis. RBX1 also interacts with proteins like SKP1 and CUL1 as part of the SCF complex which targets specific proteins for degradation. By modulating these pathways RBX1 contributes to the overall regulation of cellular growth and stress responses.

RBX1's malfunctioning links to various types of cancer and neurodegenerative diseases. In cancer altered RBX1 activity can lead to the inappropriate degradation of tumor suppressor proteins promoting uncontrolled cell division. RBX1 is also implicated in neurodegenerative disorders where misregulation of protein degradation contributes to the accumulation of damaged proteins exacerbating disease progression. Additionally the interaction of RBX1 with proteins like p53 in cancer and tau proteins in Alzheimer's illustrates its potential role in disease pathogenesis.

Target data

E3 ubiquitin ligase component of multiple cullin-RING-based E3 ubiquitin-protein ligase (CRLs) complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins, including proteins involved in cell cycle progression, signal transduction, transcription and transcription-coupled nucleotide excision repair (PubMed : 10230407, PubMed : 10579999, PubMed : 11961546, PubMed : 15983046, PubMed : 16678110, PubMed : 19112177, PubMed : 19679664, PubMed : 22748924, PubMed : 23455478, PubMed : 27565346, PubMed : 29769719, PubMed : 32355176, PubMed : 33417871, PubMed : 37844242, PubMed : 38326650, PubMed : 39504960, PubMed : 39667934, PubMed : 38316879). CRLs complexes and ARIH1 collaborate in tandem to mediate ubiquitination of target proteins, ARIH1 mediating addition of the first ubiquitin on CRLs targets (PubMed : 27565346). The functional specificity of the E3 ubiquitin-protein ligase complexes depends on the variable substrate recognition components. As a component of the CSA complex mediates ubiquitination of Pol II subunit POLR2A at 'Lys-1268', a critical TC-NER checkpoint (PubMed : 32355176, PubMed : 34526721). Core component of the Cul7-RING(FBXW8) ubiquitin ligase complex, which mediates the ubiquitination and subsequent proteasomal degradation of target proteins (PubMed : 35982156). Core component of a Cul9-RING ubiquitin ligase complex composed of CUL9 and RBX1, which mediates mono-ubiquitination of p53/TP53 (PubMed : 38605244). Recruits the E2 ubiquitin-conjugating enzyme CDC34 to the complex and brings it into close proximity to the substrate. Probably also stimulates CDC34 autoubiquitination. May be required for histone H3 and histone H4 ubiquitination in response to ultraviolet and for subsequent DNA repair. Promotes the neddylation of CUL1, CUL2, CUL4 and CUL4 via its interaction with UBE2M. Involved in the ubiquitination of KEAP1, ENC1 and KLHL41. In concert with ATF2 and CUL3, promotes degradation of KAT5 thereby attenuating its ability to acetylate and activate ATM. As part of a multisubunit complex composed of elongin BC complex (ELOB and ELOC), elongin A/ELOA, RBX1 and CUL5; polyubiquitinates monoubiquitinated POLR2A (PubMed : 19920177).
