Pleckstrins are a family of proteins found in platelets and other cells. The name derives from platelet and leukocyte C kinase substrate and the KSTR string of amino acids. The prototype protein, now called pleckstrin-1, was first identified in 1979 as the major substrate of protein kinase C in platelets. The homolog pleckstrin-2 is more widely expressed in tissues.

The pleckstrin homology domain (PH domain) was named after pleckstrin-1.
