MORC Family CW-Type Zinc Finger Protein 4 (MORC4)

MORC4 is widely expressed at low levels in normal tissues and has elevated expression in placenta and testis. The MORC4 protein contains a HATPase-c domain, CW zinc finger motif, nuclear localisation signals and a nuclear matrix-binding domain, together with a coiled-coil region. MORC4 mRNA is widely expressed at low levels in normal tissues, showing highest expression levels in placenta and testis. mRNA levels were increased in non-germinal centre-derived DLBCL and Hodgkin lymphoma cell lines, compared with germinal centre-derived DLBCL cell lines and normal B cells.The differential expression of MORC4 identifies this molecule as a potential lymphoma biomarker, whose overexpression may contribute to the immunological recognition of MORC4 by a subgroup of DLBCL patients.
