NUMA1 and lipoma: In addition to known RITA partners, such as RBP-J (recombination signal binding protein for immunoglobulin kappa J region) (Wacker et al., 2011) and LPP (lipoma-preferred partner) (Hoock et al., 2019), PRC1, NUMA1 (nuclear mitotic apparatus protein 1) and MAP1B (microtubule-associated protein 1B) were among the RITA interaction partners (Figure 3A).
