| Organism: | |

| Function: | |
Chaperone involved in tail fiber assembly and retraction. Acts as a chaperone helping to attach the long tail fibers to the virus during the assembly process. During phage assembly, twelve fibritin molecules attach to the phage neck via gp13: six molecules forming the collar and six molecules forming the whiskers. {ECO:0000269|PubMed:15659683, ECO:0000269|PubMed:23434847, ECO:0000269|PubMed:423246}. |
|
||
| Subunit: | |
Homotrimer (PubMed:9261070, PubMed:15033360, PubMed:19361528). Interacts (via N-terminal domain) with neck protein gp13; this interaction allows attachment of the fibrous collar and wiskers (PubMed:23434847). {ECO:0000269|PubMed:15033360, ECO:0000269|PubMed:19361528, ECO:0000269|PubMed:23434847, ECO:0000269|PubMed:9261070}. |
| Subcellular location: | |
Virion {ECO:0000269|PubMed:23434847}. Note=Localizes to the neck. {ECO:0000269|PubMed:23434847}. |
| Domain: | |
The central domain consists of 12 alpha-helical domains (19-40 residues long) with coiled-coil structural patterns. |
