a) Chromosomal distribution of 19,716 proteins is displayed. For every chromosome, total number of genes in target proteome, genes with protein evidence and the percentage coverage is shown as a table below the histogram. 119 proteins could not be mapped to any particular chromosome by the curated databases, among which, 116 proteins were identified at the protein level (97.5%). MT – mitochondrion; Un – unmapped to a chromosome. b) Statistics of Human Proteome Browser data categorised by the annotation features is displayed. Total number of annotations and corresponding unique number of proteins for PTMs, protein interactions, 3D structure, subcellular localization and tissue/cell line expression is displayed as a histogram and table. Note that the units on y-axis (number of annotations) are altered to accommodate the tissue/cell line expression data.
