The prevailing view is that KRAB domain proteins function as potent transcriptional repressors by recruiting TRIM28 and promoting heterochromatin spreading. However. the extent to which all KRAB domain proteins are TRIM28-dependent transcriptional repressors is c... https://halohealthcarers.shop/product-category/needles/
