Pleckstrin Homology domains

Pleckstrin Homology (PH) domains are particular motifs that can be identified by sequence analysis that bind a variety of ligands despite sharing a similar fold.  Pleckstrin, the protein for which the domain was named is a cytoskeletal protein Many proteins with a wide variety of functions contain PH domains (table1 )
