4eqk | pdb_00004eqk
From Proteopedia
Crystal structure of the cap-binding domain of polymerase basic protein 2 from influenza virus A/Hong Kong/1/68 (h3n2) with bound m7GTP
Template:ABSTRACT PUBMED 23436652
Function
[PB2_I68A4] Involved in transcription initiation and cap-stealing mechanism, in which cellular capped pre-mRNA are used to generate primers for viral transcription. Binds the cap of the target pre-RNA which is subsequently cleaved by PB1. May play a role in genome replication (By similarity).
About this Structure
