Kdm2b | Lysine-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 (By similarity). May also serve as a substrate-recognition component of the SCF (SKP1-CUL1-F-box protein)-type [...] (1309 aa) | ||||
Spns2 | Protein spinster homolog 2; Acts a a crucial lysosphingolipid sphingosine 1-phosphate (S1P) transporter involved in S1P secretion and function. S1P is a bioactive signaling molecule that regulates many physiological processes important for the development and for the immune system. Regulates levels of S1P and the S1P gradient that exists between the high circulating concentrations of S1P and low tissue levels that control lymphocyte trafficking. (549 aa) |
