Names and origin

Protein names	Recommended name: E1B protein, small T-antigen Alternative name(s): E1B 19 kDa protein Short name=E1B-19K
Organism	Human adenovirus A serotype 12 (HAdV-12) (Human adenovirus 12)
Taxonomic identifier	28282 [NCBI]
Taxonomic lineage	Viruses › dsDNA viruses, no RNA stage › Adenoviridae › Mastadenovirus › Human adenovirus A
Virus host	Homo sapiens (Human) [TaxID: 9606]

Protein attributes

Sequence length	163 AA.
Sequence status	Complete.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Putative adenovirus Bcl-2 homolog that inhibits apoptosis induced by TNF or FAS pathways, as well as p53-mediated apoptosis. Without E1B 19K function, virus production is compromised because of premature death of host cell. Interacts with Bax protein in cell lysates By similarity.
Subcellular location	Host cell membrane By similarity. Host nucleus envelope By similarity. Host nucleus lamina By similarity. Note: Associated with the plasma and nuclear membranes, and with the insoluble nuclear lamina By similarity.
Sequence similarities	Belongs to the adenoviridae E1B 19 kDa protein family.
