This entry represents the C-terminal receptor binding domain of Tip attachment protein J from Escherichia phage lambda (GpJ) and similar bacterial and viral proteins. J attaches the virion to the host receptor LamB, inducing viral DNA ejection. This domain, which determines the host specificity of the phage, shows an immunoglobulin-like fold [1,2]. Many of the proteins in this entry are annotated as fibronectin type III. This domain was previously known as DUF3672 and is normally found associated with Pfam:PF09327 and Pfam:PF13550.	Domain

J is a tail fibre protein that attaches the virion to the host receptor LamB, inducing viral DNA ejection [1,2].	Domain
