The budding yeast they determine substrate specificity. humans possess six cullins specifically Cul1 through Cul5 and Cul7. Each cullin has specific adapter proteins and substrate recognition substrates such as Elongin BC and Cul2-box proteins for Cul2 BTB (Bric-a-brac Tramtrack Broad complex) proteins for Cul3 Ddb1 and Cul4-box proteins for Cul4 Elongin BC and SOCS box… Continue reading The budding yeast they determine substrate specificity. humans possess six cullins
