Bacterial protein of unknown function. One family member (Swiss:Q97LI1) is predicted to contain a von Willebrand factor (vWF) type A domain (Smart:VWA). Another family member YeaH is predicted to be part of a conserved signalling pathway with the kinase YeaG and the SpoVR protein YcgB. The pathway may be involved in nitrogen metabolism (see Supplementary note 5 in [1].)
