CCT motif; This short motif is found in a number of plant proteins. It is rich in basic amino acids and has been called a CCT motif after Co, Col and Toc1. The CCT motif is about 45 amino acids long and contains a putative nuclear localization signal within the second half of the CCT motif. Toc1 mutants have been identified in this region.

B-box-type 1 zinc finger found in B-box (BBX) family of plant transcription factors and similar proteins; The BBX family includes a group of zinc finger transcription factors that contain one or two B-box motifs, and sometimes also feature a CCT (CONSTANS, CO-like, and TOC1) domain. They play important roles in plant growth and development, including seedling photomorphogenesis, photoperiodic regulation of flowering, shade avoidance, and responses to biotic and abiotic stresses. Their B-box motifs show high sequence similarity with B-Box-type 1 zinc finger found in tripartite motif-containing proteins (TRIMs) and are involved in mediating transcriptional regulation and protein-protein interaction in plant signaling. The type 1 B-box (Bbox1) zinc finger is characterized by a C6H2 zinc-binding consensus motif; this family contains a modified motif, C3XC2H2, where X can be D, E, C or H.

B-box-type 1 zinc finger (Bbox1); The B-box-type zinc finger is a short zinc binding domain of around 40 amino acid residues in length. It has been found in transcription factors, ribonucleoproteins and proto-oncoproteins, such as in TRIM (tripartite motif) proteins that consist of an N-terminal RING finger (originally called an A-box), followed by 1-2 B-box domains and a coiled-coil domain (also called RBCC for Ring, B-box, Coiled-Coil). The B-box-type zinc finger often presents in combination with other motifs, like RING zinc finger, NHL motif, coiled-coil or RFP domain, in functionally unrelated proteins, most likely mediating protein-protein interactions. Based on different consensus sequences and the spacing of the 7-8 zinc-binding residues, the B-box-type zinc fingers can be divided into two groups, type 1 (Bbox1: C6H2) and type 2 (Bbox2: CHC3H2). This family corresponds to the type 1 B-box (Bbox1).
