As a large family of molecules, chemokines are categorized into distinct families: C, C-C, C-X-C, and CX3C, in which a conserved cysteine motif may also include an amino acid (X) in their NH2 terminal domain.
The basic helix-loop-helix (bHLH) family of transcription factors is categorized into distinct classes on the basis of biochemical and functional criteria and each member protein contains an HLH domain composed of two amphipathic helixes separated by a loop and a basic DNA-binding domain (1– 3).
Crowdfunding can loosely be categorized into four distinct models, primarily based on the goals structured by both entrepreneurs and supporters: donation-, lequity-, equity-, and reward-based models (Mollick 2014).
The overall distribution of Pcb and IsiA-like peptides can be categorized into three distinct groups that reflect the phylogenetic distribution of these genes from cultured representatives [6], [19], [20], [29].
Inferred from Ddc-gal4-driven marker gene expression (Fig. 6), DDC immunostainings (Fig. 7; Fig. S3), and double labeling experiments with antibodies against 5-HT and TH (Fig. S4), DDC neurons can be categorized into five distinct neuron groups: The first group consists of segmentally reiterated DDC neuron pairs with somata in the ventral cortex below the CI fascicles.
However, these six studies can be categorized into three distinct HLB disease stages (see Table 1).
Recently, it has been suggested [ 8] that non-hydrolytic disruptive proteins can be categorized into two distinct groups.
Based on their physicochemical properties they can be categorized into two distinct groups: liquid-like and crystalline.
Taken together, these results provide evidence that rare exonic SNPs should be categorized into two distinct groups those with derived minor alleles and those with ancestral minor alleles.
