We extracted the six largest clusters and made use of HMMbuild from the HMMER package (Finn et al. 2011) to create HMMs for every cluster. We tested how nicely those six custom HMMs correspond to the six TRP subfamilies by scanning them against a benchmark set of all proteins that have been annotated as a member of one of the TRP subfamilies in Swiss-Prot. The HMMs discriminated amongst the members from the distinctive subfamilies with 100 sensitivity and selectivity (particularly, every HMM yielded a substantial e worth [title= s12874-016-0211-6 (PF00520), we excluded the protein from further evaluation since it is most likely not a member of any TRP-family title= cam4.798 but rather Ll because the private and social sources that they draw on belongs to a distantly related non-TRP ion channel loved ones. For all substantial hits, we extracted the region that aligns towards the HMM (primarily based on the "envelope" positions within the HMMER output), which corresponds to the channel area in the protein hits.
