RLBP1 phylogeny and sequence alignment. (A) Maximum-likelihood tree (RAXML) of the RLBP1 and Clavesin families. Bayesian posterior probabilities (left value) higher than 0.90 and ML bootstrap (500 replicates, right value) higher than 50% are indicated below or above branches. (B) Conserved sites of known functional relevance in RLBP1. The amino acids W166, Y180, F198, C199, M209, Q211, M223, V224, M226, and W245 have been shown to be critically important for RLBP1 to function. These amino acids are well-conserved among vertebrate RLBP1s but largely absent from Clavesins and TTPAs. L.asellus RLBP1 exhibits 8 of 10 conserved residues
