part of cell cortex cortical dynamic polarity patch tb cellular_component dynamic polarity patch at the cell cortex A region of the cell cortex that contains a higher concentration of growth polarity factors than the surrounding cortex and that changes position over time. An example is found in fission yeast cells during early mating, in which the GTPase Cdc42 dynamically to discrete zones within the cortex prior to shmoo formation.
