Titin yog protein ntau ntau ntawm striated nqaij . Titin tus thawj lub luag haujlwm yog Txhawm rau kom ruaj khov cov ntaub ntawv tuab, nruab nrab ntawm cov ntaub nyias nyias, tiv thaiv kom tsis txhob overstretching ntawm sarcomere, thiab kom rov qab cov sarcomere zoo li lub caij nplooj ntoos hlav tom qab nws yog ncab.
Ua raws li qhov no, qhov twg titin pom nyob rau hauv ib lub sarcomere?
