WebSep 15, 2014 · Chemotaxis analysis revealed defective cAMP chemotaxis in the stlA null mutant. cAMP chemotaxis was restored by MPBD addition during early stage development. Assay for cAMP relay response revealed that the stlA null mutant had lower cAMP accumulation during aggregation, suggesting lower ACA activity than the wild type strain. 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.
