This entry represents the Cache domain found in the sensor protein kinase WalK (or YycG) from bacteria. The WalK protein, alongside its response regulator WalR, is part of a two-component signal transduction system involved in diverse cellular processes, including cell wall metabolism, virulence regulation, biofilm production, among many other cellular processes [1, 2]. This domain is extracellular and is involved in WalK dimerization necessary for protein function [3].	Domain
