      Background InformationShutoff protein (UniProt: P24933; also known as 100 kDa protein, (p100K), 100K-chaperone protein, L4-100K, Shutoff protein 100K) is encoded by the L4 gene (Gene ID: 2653005) in human Adenovirus 5. Adenovirus 5 belongs to the Adenoviridae family of non-enveloped viruses that are characterized by linear, double-stranded DNA genomes. Their capsid is an icosahedron that contains at least 12 different viral proteins. Adenovirus 5 is commonly used for gene transfer experiments due to its ability to infect a wide group of different cell types. It can harbor large genes in its genome incorporated via homologous recombination techniques. Adenovirus assembly protein L4-100K is a multifunctional protein critical for the adenovirus replication cycle. It selectively that inhibits host translation while promoting late viral translation by ribosome shunting. Also, assists in the nuclear export of late viral mRNAs, ensuring their translation in the cytoplasm. L4-100K exists as a monomer and interacts with hexon protein. This interaction allows chaperoning and trimerization of hexon proteins, aiding in their proper folding and assembly into the virion capsid. It contains a short binding region (aa 280-345) that is essential for binding to the tripartite leader sequence of viral late mRNAs and recruits host eIF4G. L4-100K is expressed in the late phase of viral replicative cycle and its expression is tightly regulated by the viral transcriptional machinery and coincides with the synthesis of other late viral proteins necessary for virion assembly. L4-100K protein is predominantly localized in the cytoplasm of infected cells and it shuttles between the nucleus and cytoplasm. Its involvement in the nuclear export of viral mRNAs, enhancement of translation, inhibition of host protein synthesis, and chaperoning of hexon proteins underscores its importance in viral replication and pathogenicity. Studies demonstrate that L4-100K is a GrB substrate that prevents cytotoxic lymphocyte granule-induced apoptosis in infected target cells by potently inhibiting GrB. 100K is the first viral protein described that exclusively targets the GrB pathway and it represents a novel class of viral protease inhibitor, in which an essential, multifunctional viral protein, which is vulnerable to specific proteolysis by GrB, expresses inhibitory function against that protease.
