UBC9 is overexpressed in certain tumors, such as lung adenocarcinoma, ovarian carcinoma and melanoma, which implies that it has special clinical significance.
Equally important, we provide evidence that the ubiquitin-conjugating enzyme, Ubc9, is expressed at high levels in melanoma-positive lymph nodes, and that it plays a crucial role in preventing advanced-stage melanomas from undergoing chemotherapy-induced apoptosis.

Recent reports indicate that Ubc9, the single SUMO E2 enzyme catalyzing the conjugation of SUMO to target proteins, is overexpressed in certain tumors, such as lung adenocarcinoma, ovarian carcinoma and melanoma, suggestive of its clinic significance.
As Ubc9 is the sole E2-conjugating enzyme required for sumoylation, and, in particular, Ubc9 is upregulated in an increasing number of human malignancies, such as ovarian carcinoma, melanoma and lung adenocarcinoma, it is a potential target for cancer therapy.
The CDKN2C gene coding for the cyclin-dependent kinase inhibitor p18 is localized on 1p32, a region frequently involved in chromosomal changes in melanomas and other tumors.
