Ubiquitin activating enzyme 1 (Uba1) encodes an E1 enzyme involved in protein ubiquitylation. It contributes to multiple processes including regulation of Ras-ERK signaling, autophagy, apoptosis and tissue growth; Belongs to the ubiquitin-activating E1 family.

E3 ubiquitin-protein ligase UBR1; E3 ubiquitin-protein ligase which is a component of the N-end rule pathway. Recognizes and binds to proteins bearing specific N- terminal residues that are destabilizing according to the N-end rule, leading to their ubiquitination and subsequent degradation. Belongs to the UBR1 family.

Ubiquitin-conjugating enzyme variant 1A (Uev1A) encodes a conserved protein that contributes to ubiquitin conjugating enzyme activity, but not catalytically, since it lacks the conserved cysteine residue essential for ubiquitin conjugation. It regulates genomic integrity, IMD pathway-mediated innate immunity, JNK-pathway mediated cell death and tumor invasion.

Ubiquitin-40S ribosomal protein S27a; Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-48-linked is involve [...]

DNA polymerase zeta catalytic subunit; As the catalytic subunit of the DNA polymerase zeta complex, plays a crucial role in translesion DNA synthesis (TLS) and various DNA repair mechanisms. Lacks an intrinsic 3'-5' exonuclease activity and thus has no proofreading function. During homologous recombination (HR) repair, has a overlapping role with the error-prone translesion polymerase eta to initiate repair synthesis which is completed by end joining or another polymerase that can bind and reinitiate synthesis. May participate in the Rrp1- dependent base excision repair (BER) pathway r [...]

Proliferating cell nuclear antigen 2; Likely to be an auxiliary protein of DNA polymerase delta complex and is probably involved in the control of DNA replication and repair by increasing the polymerase's processibility. May function independently of PCNA during DNA repair.

Proliferating cell nuclear antigen; Likely to be an auxiliary protein of DNA polymerase delta complex and is probably involved in the control of DNA replication and repair by increasing the polymerase's processibility. Belongs to the PCNA family.

Ubiquitin-60S ribosomal protein L40; [Ubiquitin]: exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-48-linked is invol [...]

Antimeros, isoform A; Antimeros (atms) encodes a component of the PAF1 complex (together with the products of Atu, hyx, Rtf1 and Ctr9). The PAF1 complex physically interacts with components of the basal transcription machinery and sequence-specific transcription factors to control histone modifications and pause release.
