It is a high\u2011affinity binding partner of TGF\u2011\u03b2 superfamily members including myostatin, activin, and BMPs, and functions as a potent antagonist of myostatin\u2011mediated muscle growth suppression<\/span><span class=\"\">.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">\u00a0What are the primary research applications for Follistatin-344?<\/span><\/strong><br \/>\n<span class=\"\">Follistatin-344 is used in muscle biology and myostatin inhibition research (muscle hypertrophy, satellite cell activation, sarcopenia), metabolic and endocrine system research (\u03b2\u2011cell proliferation, insulin sensitivity), tissue fibrosis and regeneration research (hepatic fibrosis, tissue repair), bone and skeletal tissue research, and cancer and neurodevelopmental research.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">How does Follistatin-344 inhibit myostatin?<\/span><\/strong><br \/>\n<span class=\"\">Follistatin-344 binds directly to myostatin, preventing it from activating its receptor (ActRIIB) on muscle cells<\/span><span class=\"\">.
