This regulatory genomic response of the enterocyte would result in an increase in the brush border membrane content of CaT1 calcium influx channels that could function as a gatekeeper mechanism to augment the rate of calcium entry across the apical membrane [ 9 ] . However, given that there is a Ca-dependent negative feedback mechanism to limit calcium entry through the channel by maintaining the channel in the closed position [ 14 15 ] there must be a way to remove calcium from the vicinity of the cytosolic face of the channel to optimize and sustain calcium influx rates.
