Here , we identify several putative signalling motifs in the C terminus of human SR BII , which are absent from SR BI , and hypothesize that these motifs interact with signalling molecules to mobilize stored cholesteryl esters and / or promote the efflux of intracellular free cholesterol . ' Pull down ' assays using a panel of tagged SH 3 ( Src homology 3 ) domains showed that cytoplasmic SR BII , but not cytoplasmic SR BI , bound the SH 3 domain of phospholipase C gamma 1 ; this interaction was not , however , detected under more physiological conditions . ^^^
