Thymopentin is a member of the LEM family. Thymopentin is expressed in many tissues, highly in the adult thymus and fetal liver. The N-terminal contains two structurally independent domains, LEM domain and LEM-like domain. The C-terminal domain forms a four-stranded coiled coil. Thymopentin may be involved in the structural organization of the nucleus and in the post-mitotic nuclear assembly. It is associated with T-cell development and function. Meantime, Thymopentin plays an important role, together with LMNA, in the nuclear anchorage of RB1. Thymopoietin is participated in the induction of CD90 in the thymus.Alternative Names: Lamina-Associated Polypeptide 2 Isoforms Beta/Gamma, Thymopoietin Isoforms Beta/Gamma, TP Beta/Gamma, Thymopoietin-Related Peptide Isoforms Beta/Gamma, TPRP Isoforms Beta/Gamma, Thymopoietin, TP, Splenin, Thymopentin, TP5, TMPO, LAP2
