Sumo2 | Small ubiquitin-related modifier 2; Ubiquitin-like protein that can be covalently attached to proteins as a monomer or as a lysine-linked polymer. Covalent attachment via an isopeptide bond to its substrates requires prior activation by the E1 complex SAE1-SAE2 and linkage to the E2 enzyme UBE2I, and can be promoted by an E3 ligase such as PIAS1-4, RANBP2 or CBX4. This post-translational modification on lysine residues of proteins plays a crucial role in a number of cellular processes such as nuclear transport, DNA replication and repair, mitosis and signal transduction. Polymeric SUMO [...] (95 aa) | ||||
Nkx2-6 | Homeobox protein Nkx-2.6; Acts as a transcriptional activator (By similarity). In conjunction with NKX2-5, may play a role in both pharyngeal and cardiac embryonic development. (289 aa) |
