Our recent findings implicate the SNAP receptor ( SNARE ) protein SNAP 23 and secretory carrier membrane protein 2 ( SCAMP 2 ) as regulators of this process . ^^^ We also review recent findings showing that the candidate exocytotic SNAREs SNAP 23 and syntaxin 4 colocalize with SCAMPs , especially SCAMP 2 , and that SCAMP 2 is likely to be a partner in the compound exocytotic process . . ^^^
