SMT3 suppressor of mif two 3 homolog 2 (S. cerevisiae); Ubiquitin-like protein that can be covalently attached to proteins as a monomer or as a lysine-linked polymer. Covalent attachment via an isopeptide bond to its substrates requires prior activation by the E1 complex SAE1-SAE2 and linkage to the E2 enzyme UBE2I, and can be promoted by an E3 ligase such as PIAS1-4, RANBP2 or CBX4. This post-translational modification on lysine residues of proteins plays a crucial role in a number of cellular processes such as nuclear transport, DNA replication and repair, mitosis and signal transduc [...] (95 aa)

solute carrier family 19 (folate transporter), member 1; Transporter for the intake of folate. Uptake of folate in human placental choriocarcinoma cells occurs by a novel mechanism called potocytosis which functionally couples three components, namely the folate receptor, the folate transporter, and a V-type H(+)-pump (591 aa)

zinc finger protein 161 homolog (mouse); Transcriptional activator of the dopamine transporter (DAT), binding it’s promoter at the consensus sequence 5’- CCTGCACAGTTCACGGA-3’. Binds to 5’-d(GCC)(n)-3’ trinucleotide repeats in promoter regions and acts as a repressor of the FMR1 gene. Transcriptional repressor of MYC and thymidine kinase promoters (449 aa)

listerin E3 ubiquitin protein ligase 1 (1812 aa)

lysine (K)-specific demethylase 2B; Histone demethylase that demethylates ’Lys-4’ and ’Lys- 36’ of histone H3, thereby playing a central role in histone code. Preferentially demethylates trimethylated H3 ’Lys-4’ and dimethylated H3 ’Lys-36’ residue while it has weak or no activity for mono- and tri-methylated H3 ’Lys-36’. Preferentially binds the transcribed region of ribosomal RNA and represses the transcription of ribosomal RNA genes which inhibits cell growth and proliferation. May also serve as a substrate-recognition component of the SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin [...] (1336 aa)

mitochondrial ribosomal protein L39 (353 aa)

PAS domain containing serine/threonine kinase; Serine/threonine-protein kinase involved in energy homeostasis and protein translation. Phosphorylates EEF1A1, GYS1, PDX1 and RPS6. Probably plays a role under changing environmental conditions (oxygen, glucose, nutrition), rather than under standard conditions. Acts as a sensor involved in energy homeostasis- regulates glycogen synthase synthesis by mediating phosphorylation of GYS1, leading to GYS1 inactivation. May be involved in glucose-stimulated insulin production in pancreas and regulation of glucagon secretion by glucose in alpha c [...] (1323 aa)

5’-3’ exoribonuclease 1; Major 5’-3’ exoribonuclease involved in mRNA decay. Required for the 5’-3’-processing of the G4 tetraplex-containing DNA and RNA substrates. The kinetic of hydrolysis is faster for G4 RNA tetraplex than for G4 DNA tetraplex and monomeric RNA tetraplex. Binds to RNA and DNA (By similarity). Plays a role in replication-dependent histone mRNA degradation. May act as a tumor suppressor protein in osteogenic sarcoma (OGS) (1706 aa)
