Members of this protein family are found occasionally on plasmids such as the Pseudomonas putida toluene catabolic TOL plasmid pWWO_p085. Usually, however, they are found on the bacterial main chromosome in regions flanked by markers of conjugative transfer and/or transposition.

MreC (murein formation C) is involved in the rod shape determination in E. coli, and more generally in cell shape determination of bacteria whether or not they are rod-shaped. Cells defective in MreC are round. Species with MreC include many of the Proteobacteria, Gram-positives, and spirochetes.

The majority of the plant MADS proteins share a stereotypical MIKC structure. It comprises (from N- to C-terminal) an N-terminal domain, which is, however, present only in a minority of proteins; a MADS domain (see PDOC00302 from PROSITEDOC, IPR002100 from INTERPRO), which is the major determinant of DNA-binding but which also performs dimerisation and accessory factor binding functions; a weakly conserved intervening (I) domain, which constitutes a key molecular determinant for the selective formation of DNA-binding dimers; a keratin-like (K-box) domain, which promotes protein dimerisation; and a C-terminal (C) domain, which is involved in transcriptional activation or in the formation of ternary or quaternary protein complexes. The 80-amino acid K-box domain was originally identified as a region with low but significant similarity to a region of keratin, which is part of the coiled-coil sequence constituting the central rod-shaped domain of keratin [, , ]. The K-box protein-protein interaction domain which mediates heterodimerization of MIKC-type MADS proteins contains several heptad repeats in which the first and the fourth positions are occupied by hydrophobic amino acids suggesting that the K-box domain forms three amphipathic alpha-helices referred to as K1, K2, and K3 [].; GO: 0003700 sequence-specific DNA binding transcription factor activity, 0006355 regulation of transcription, DNA-dependent, 0005634 nucleus

Slk19 is a yeast member and it may play an important role in the timing of nuclear migration. It may also participate, directly or indirectly, in the maintenance of centromeric tensile strength during mitotic stagnation, for instance during activation of checkpoint controls, when cells need to preserve nuclear integrity until cell cycle progression can be resumed [].
