Timopoietin (polipeptid vezan za laminu 2, LAP2) je protein koji je kod ljudi kodiran TMPO genom.[1][2] LAP2 je protein unutrašnje membrane jedra.[3]

Timopoietin učestvuje u indukciji CD90 proteina u grudnu žlezdu. Gen timopoetina kodira tri alternativno splajsovane iRNK molekula koji kodiraju proteine sa 75 kDa (alfa), 51 kDa (beta) i 39 kDa (gama). Oni su izraženi u većini ćelijskih tipova. Ljudski TMPO gen se nalazi u hromozomsko opsegu 12q22 i sastoji se od osam eksona.

Interakcije[uredi - уреди]

Timopoietin formira interakcije sa barijerom za autointegracioni faktor 1,[4] AKAP8L,[5][6] LMNB1[7][8] i LMNA.[9][10]
