[[http://www.uniprot.org/uniprot/VG10_BPT4 VG10_BPT4]] Structural component of the baseplate.  
[https://www.uniprot.org/uniprot/BP10_BPT4 BP10_BPT4] Baseplate protein that is part of the baseplate wedge and that connects the short tail fibers to the baseplate (PubMed:16554069). During infection, the baseplate undergoes a conformational change from a dome-shaped to a star-shaped structure. At this point, gp10 rotates and acts as a lever that unfolds the short tail fibers, which then interact with host cell surface receptors. Involved in the tail assembly.<ref>PMID:16554069</ref> <ref>PMID:21129200</ref>

== Publication Abstract from PubMed ==
The success of tailed bacteriophages to infect cells far exceeds that of most other viruses on account of their specialized tail and associated baseplate structures. The baseplate protein gene product (gp) 10 of bacteriophage T4, whose structure was determined to 1.2 A resolution, was fitted into the cryo-electron microscopy structures of the pre and post-infection conformations of the virus. gp10 functions as a molecular lever that rotates and extends the hinged short tail fibers to facilitate cell attachment. The central folding motif of the gp10 trimer is similar to that of the baseplate protein gp11 and to the receptor-binding domain of the short tail fiber, gp12. The three proteins comprise the periphery of the baseplate and interact with each other. The structural and functional similarities of gp10, gp11, and gp12 and their sequential order in the T4 genome suggest that they evolved separately, subsequent to gene triplication from a common ancestor. Such events are usual in the evolution of complex organelles from a common primordial molecule.
