Goat anti Human CBX3 antibody recognizes human chromobox homolog 3 (CBX3), a ~20 kDa protein. It binds histone H3 tails methylated at lysine 9, repressing transcription. CBX3 also interacts with lamin B receptor, forming a functional kinetochore through interaction with MIS12 complex proteins. This dual binding may contribute to the association of heterochromatin with the inner nuclear membrane.
