The Desmoplakin Hinge Domain Confers a Reversible Conformational Change in Response to Acute External Force
Desmosomes provide mechanical integrity to tissues that experience strain, yet how mechanical force is sensed and distributed within the desmosomal plaque remains poorly understood. Here we identify the hinge within the desmoplakin (DP) head domain is required for repositioning the DP tail in response to acute uniaxial mechanical stretch. This repositioning occurs within 30 seconds of applied…
