The overall features of transmembrane kinases (TMKs) from different kingdoms. (A) The pipeline used for cross-kingdom identification of transmembrane kinases (TMKs). Model organisms were selected according to Hedges [15]. The profile hidden Markov models from Pfam-A were used for annotating three types of protein kinases (H, histidine; S/T/Y, serine/threonine/tyrosine; AA, amino acid) and other domains by HMMER v3.3.2. The transmembrane (TM) topology was predicted using the deepTMHMM server v1.0.13 (https://dtu.biolib.com/DeepTMHMM). (B) Comparison of the TMK proportions in the proteomes among five groupings. Different letters above the boxplots indicate significant difference (one-way ANOVA, n = 18–39). (C) The percentages of different TMK types (H, S/T/Y, and AA) in the five groupings. (D) Major TM topology types of TMKs in each grouping. N, amino-terminus; C, carboxyl-terminus; TM, transmembrane; ECD, extracellular domain.
