mitocarta: Mitocarta: an inventory of mammalian mitochondrial genes
In hirscheylab/mitocarta: Mitocarta Data Set and Utility Functions

MitoCarta2.0 is an inventory of 1158 human genes encoding proteins with strong support of mitochondrial localization. To generate this inventory, the Mootha lab at MGH performed mass spectrometry of mitochondria isolated from fourteen tissues, assessed protein localization through large-scale GFP tagging/microscopy, and integrated these results with six other genome-scale datasets of mitochondrial localization, using a Bayesian approach. MitoCarta2.0, released 2015, is an update from the MitoCarta1.0 inventory published in Cell, 2008.

A data frame with 19,244 rows and 43 variables:

training_dataset: Tmito, Tnot_mito, or T_possible_mito (indicating evidence based on NCBI GO mitochondrial annotation or MitoP2 database, but not in Tmito)
human_gene_id: NCBI Entrez Gene ID for human ortholog of mouse gene (based on reciprocal BLASTP hit, expect<1e-3)

description: NCBI Entrez gene description
ensembl_gene_id: Ensembl Gene Identifier (based on Ensembl mapper)
protein_length: Length of longest RefSeq protein isoform
target_p_score: TargetP confidence score (1-5, 1 is most confident) of mitochondrial targeting signal. Score 0 indicates no mitochondrial prediction
mito_domain_score: MitoDomain indicates exclusively mito domain; SharedDomain indicates shared mito & non-mito domain; NonMitoDomain indicates exclusively non-mito domain; NA indicates unknown

pgc_induction_score: Foldchange in transcript induction following overexpression of PGC1a, known to induce mitochondrial biogenesis
yeast_mito_homolog_score: OrthologMitoHighConf (HomologMitoHighConf) if yeast ortholog (homolog) is annotated mitochondrial in SGD with high confidence; OrthologMitoLowConf (HomologMitoLowConf) if yeast ortholog (homolog) is annotated mitochondrial in SGD with low confidence (dual localized or only based on high throughput data), NoMitoHomolog indicates no yeast homolog or homolog is not annotated mitochondrial in SGD
rickettsia_homolog_score: Ortholog if 1:1 ortholog between mouse and Rickettsia prowazekii; Homolog if homology between mouse and Rickettsia prowazekii, otherwise NoHomolog
