OF MUSCLE TISSUE
ACTININ – HOLDS THIN FILAMENTS
IN THE Z-DISK (LINE)
MYOMESIN – HOLDS MYOSIN FILAMENTS IN THE
REGION OF M-LINETITIN (CONNECTIN) – LINKS THE ENDS OF THICK FILAMENTS TO
THE Z-LINE
DESMIN – LINK ADJACENT MYOFIBRILS TO EACH OTHER
C-PROTEIN – MYOSIN BINDING PROTEIN
DYSTROPHIN – PLASMA MEMBRANE PROTEIN, BRIDGES ACTIN
FILAMENTS TO THE EXTERNAL LAMINA TO TRANSFER THE INTERNAL
FORCES OF CONTRACTION TO THE EXTERNAL TISSUES
