Interaction in humans has been curated in BioGRID interaction database on the base of [105], but it was not found in the main text of the article or in Suppl. files

Putative homologs of human SNRPC and SNRPN were found interacting in yeast [106]

Human PRKD1 (=PKD) and MAPK8 (=JNK), which is MAPK9 homolog, were found interacting in humans [108]

  1. a DEG, differentially expressed gene in mouse hypothalamic AGRP- or POMC-expressing neurons according to [49]
  2. b TSEA gene. Revealed by TSEA (see Gene expression analysis section) as brain-specific at the pSI threshold = 0.05
  3. c The rank was defined for each gene in the network Experimental_brain-specific on the base of the number of first neighbors
  4. d In [103] NDUFS3 was noted as a precursor of NADH-ubiquinone oxidoreductase flavoprotein 3 isoform a (see Supplemental data in [103])
