TOM1/YDR457W Summary Help

Standard Name TOM1 1
Systematic Name YDR457W
Feature Type ORF, Verified
Description E3 ubiquitin ligase of the hect-domain class; has a role in mRNA export from the nucleus and may regulate transcriptional coactivators; involved in degradation of excess histones; interacts with Dia2p and is required for Dia2p degradation; required to target Cdc6p for ubiquitin-mediated destruction during G1 phase (2, 3, 4, 5, 6, 7, 8)
Name Description Temperature dependent Organization in Mitotic nucleus
