Function

[MEMO1_HUMAN] May control cell migration by relaying extracellular chemotactic signals to the microtubule cytoskeleton. Mediator of ERBB2 signaling. The MEMO1-RHOA-DIAPH1 signaling pathway plays an important role in ERBB2-dependent stabilization of microtubules at the cell cortex. It controls the localization of APC and CLASP2 to the cell membrane, via the regulation of GSK3B activity. In turn, membrane-bound APC allows the localization of the MACF1 to the cell membrane, which is required for microtubule capture and stabilization. Is required for breast carcinoma cell migration.^[1] ^[2]

Publication Abstract from PubMed

Memo (mediator of ErbB2-driven cell motility) is a 297-amino-acid protein recently shown to co-precipitate with the C terminus of ErbB2 and be required for ErbB2-driven cell motility. Memo is not homologous to any known signaling proteins, and how it mediates ErbB2 signals is not known. To provide a molecular basis for understanding Memo function, we have determined and report here the 2.1A crystal structure of human Memo and show it be homologous to class III nonheme iron-dependent dioxygenases, a structural class that now includes a zinc-binding protein of unknown function. No metal binding or enzymatic activity can be detected for Memo, but Memo does bind directly to a specific ErbB2-derived phosphopeptide encompassing Tyr-1227 using its vestigial enzymatic active site. Memo thus represents a new class of phosphotyrosine-binding protein.

Memo is homologous to nonheme iron dioxygenases and binds an ErbB2-derived phosphopeptide in its vestigial active site.,Qiu C, Lienhard S, Hynes NE, Badache A, Leahy DJ J Biol Chem. 2008 Feb 1;283(5):2734-40. Epub 2007 Nov 28. PMID:18045866^[3]
