チモポイエチン[5][6]（Thymopoietin、Lamina-associated polypeptide 2 (LAP2), isoforms beta/gamma）はタンパク質の一つ。ヒトではTMPO 遺伝子にコードされる[7][8]。LAP2は、核内膜タンパク質である[9]。
胸腺でのCD90の誘導に関与するタンパク質である。TMPO遺伝子はすべての細胞で発現しており、選択的スプライシングにより75kDa（α）、51kDa（β）、39kDa（γ）のタンパク質をコードする。ヒトTMPO 遺伝子は染色体バンド12q22に位置し、8つのエクソンから構成される。TMPOαは細胞核に散在し、TMPOβとγは核膜に局在する。TMPOβはマウスタンパク質LAP2のヒトホモログである。LAP2は有糸分裂期にラミンB1のリン酸化を制御することによってラミンB1と染色体を結合させ、核構造を制御している[10]。
相互作用
[編集]チモポイエチンは、自己統合障壁因子1[11]（BAF1）、AKAP8L[12][13]、LMNB1[14][15]、LMNA[16][17]と相互作用する事が示されている。
