A PF00097 zf-C3HC4 Zinc finger, C3HC4 type (RING finger) Domain The C3HC4 type zinc-finger (RING finger) is a cysteine-rich domain of 40 to 60 residues that coordinates two zinc ions, and has the consensus sequence: C-X2-C-X(9-39)-C-X(1-3)-H-X(2-3)-C-X2-C-X(4-48)-C-X2-C where X is any amino acid [1]. Many proteins containing a RING finger play a key role in the ubiquitination pathway [2]. PFAM PF00097
B PF14835 zf-RING_6 zf-RING of BARD1-type protein Domain The RING domain of the breast and ovarian cancer tumour-suppressor BRCA1 interacts with multiple cognate proteins, including the RING protein BARD1. Proper function of the BRCA1 RING domain is critical, as evidenced by the many cancer-predisposing mutations found within this domain. A dimer is formed between the RING domains of BRCA1 and BARD1. The BRCA1-BARD1 structure provides a model for its ubiquitin ligase activity, illustrates how the BRCA1 RING domain can be involved in associations with multiple protein partners and provides a framework for understanding cancer-causing mutations at the molecular level [1]. The corresponding BRCA1-RING domain is on family zf-C3HC4_2, Pfam:PF13923. PFAM PF14835
