This entry represents the zinc finger domain of Regulating synaptic membrane exocytosis protein 2 (RIM2a) and related proteins. This domain alone is responsible for the interaction with Munc13-1 by engaging with the Munc13-1 C2A domain [1]. Structurally, this domain is similar to FIVE zinc fingers.	Domain
