WebApr 1, 2011 · Chemotaxis to folate is mildly reduced in cells lacking ERK2 but absent in cells lacking the Gα4 or Gβ subunit (60, 63, 65). Likewise, chemotaxis to cAMP requires G proteins (i.e., Gα2 and Gβ subunits) but not ERK2 . Therefore ERK2 appears to play only a minor role in both chemotaxis responses. WebAug 20, 2024 · These cells respond to cAMP stimuli by moving toward the center (chemotaxis) and secreting additional cAMP (signal relay).
