trx | Histone-lysine N-methyltransferase trithorax; Histone methyltransferase that trimethylates 'Lys-9' of histone H3 (H3K9me3). H3 'Lys-9' methylation represents a specific tag for epigenetic transcriptional activation. Functions in segment determination through interaction with genes of bithorax (BX-C) and antennapedia (ANT-C) complexes. Acts as an activator of BX-C. Involved in the very early regulation of homeotic genes expressed only in the posterior region of the embryo. (3726 aa) | ||||
HIP-R | Hsc70-interacting protein 1; One HIP oligomer binds the ATPase domains of at least two Hsc70 molecules dependent on activation of the Hsc70 ATPase by Hsp40. Stabilizes the ADP state of Hsc70 that has a high affinity for substrate protein. Through its own chaperone activity, it may contribute to the interaction of Hsc70 with various target proteins (By similarity). (377 aa) |
