# Summary

MAPK7, also known as ERK5, plays a crucial role in various cellular processes, particularly in response to stress and in cancer development and progression. It functions as a member of the mitogen-activated protein kinase (MAPK) family and is activated by diverse stimuli.[^1]

In the context of cancer, ERK5's activity has been linked to cell proliferation and tumorigenesis. Specifically, ERK5 activation can lead to cell cycle progression through the G2-M phase by activating the NFκB pathway.[^2] ERK5 overexpression has been correlated with decreased disease-free survival in breast cancer patients[^3], and inhibiting ERK5 can decrease cancer cell proliferation and increase sensitivity to certain therapies.[^3][^4] In some cases, the activation of ERK5 is directly related to the expression of other genes and/or kinases to promote cell proliferation.[^5] In colorectal cancer, miR-143 can interfere with ERK5 signaling.[^4]

In embryonic development, ERK5 is essential for proper development and is necessary for vascular system formation and cell survival.[^6]

This summary was generated by summarizing the top 50 most cited paper abstracts that mention this gene using gemini-flash (DeepDive).
