摘要
When muscles are stretched, the giant protein titin develops passive force. Titin's force performs important functions that include maintaining the structural integrity of the sarcomere and triggerng signal transduction pathways. We propose that the mechanical properties of titin can be tuned according to the mechanical demands placed on muscle, using mechanisms that include alternative splicing and posttranslational modifications.
