SV40 Large T Antigen
Introduction
The SV40 large T antigen is a multifunctional regulatory protein encoded by Simian Virus 40, belonging to the AAA+ family of helicases [1]. It is responsible for initiation of DNA replication, regulation of transcription and alteration of the host cell cycle to promote infectivity. Large T antigen is an early gene product of SV40 and is translated via differential mRNA splicing.
Structure
T-antigen consists of an N-terminal J domain, a central origin-binding domain, and a C-terminal helicase domain [1].
