Title: Effect of XPA gene mutations on UV-induced immunostaining of PCNA in fibroblasts from xeroderma pigmentosum group A patients. Author: Miura M, Sasaki T. Journal: Mutat Res; 1996 Sep 02; 364(1):51-6. PubMed ID: 8814338. Abstract: We have investigated the relationship between XPA gene mutations and PCNA complex formation in the nucleotide excision repair (NER) process utilizing cells derived from various xeroderma pigmentosum group A (XP-A) patients. The PCNA complex formation was detected by PCNA immunostaining following methanol fixation. Results indicated that UV-induced PCNA staining at early stages was well correlated to the function of XPA protein and provided evidence that XPA protein-related recognition step was tightly linked to PCNA-associated events in the NER process in vivo.[Abstract] [Full Text] [Related] [New Search]
