Protein Domain : Adenovirus small t-antigen, E1B 19kDa protein IPR002924

Type	Family
Description	This family consists of adenovirus E1B 19kDa protein or small t-antigen. The E1B 19kDa protein inhibits E1A induced apoptosis and hence prolongs the viability of the host cell [ ]. It can also inhibit apoptosis mediated by tumour necrosis factor alpha and Fas antigen []. E1B 19kDa blocks apoptosis by interacting with and inhibiting the p53-inducible and death-promoting Bax protein []. The E1B region of adenovirus encodes two proteins E1B 19kDa the small t-antigen as found in this family and E1B 55kDa thelarge t-antigen which is not found in this family; both of these proteins inhibit E1A induced apoptosis [].
Short Name	Adenovir_t-Ag_E1B_19kDa
