Lipoma Preferred Partner (LPP, LIM Domain-containing Preferred Translocation Partner in Lipoma)

Lipoma preferred partner (LPP) is encoded by the preferred fusion partner gene of the high mobility group protein HMGI-C. LPP is frequently affected by chromosomal translocations in a major group of soft tissue lipomas, as well as in a parosteal lipoma and in pulmonary chondroid hamartomas. The resulting fusion proteins comprise three DNA binding domains of HMGI-C fused to two or three C-terminal LIM domains of LPP and a reciprocal product, respectively. Expression of a HMGI-C/LPP fusion protein causes malignant transformation of fibroblasts. Similar to its relatives zyxin and TRIP (thyroid receptor...
