Memo (mediator of ErbB2-driven cell motility) is co-precipitated with the C terminus of ErbB2, a protein involved in cell motility. This subfamily is composed of Memo (mediator of ErbB2-driven cell motility) and similar proteins. Memo is a protein that is co-precipitated with the C terminus of ErbB2, a protein involved in cell motility. It is required for the ErbB2-driven cell mobility and is found in protein complexes with cofilin, ErbB2 and PLCgamma1. However, Memo is not homologous to any known signaling proteins, and its function in ErbB2 signaling is not known. Structural studies show that Memo binds directly to a specific ErbB2-derived phosphopeptide. Memo is homologous to class III nonheme iron-dependent extradiol dioxygenases, however, no metal binding or enzymatic activity can be detected for Memo. This subfamily also contains a few members containing a C-terminal AMMECR1-like domain. The AMMECR1 protein was proposed to be a regulatory factor that is potentially involved in the development of AMME contiguous gene deletion syndrome. |
