The TPM domain family is named after the three founding proteins TLP18.3, Psb32 and MOLO-1. TPM domains have a characteristic fold (αβαβαββαα or βαβαββαα) composed of α helices (3+3 or 2+3) flanking four central β strands. The TPM fold has not been found in other protein domains to date. TPM was previously referred to as "DUF477" and "Repair_PSII". In plants, the TPM domain-containing proteins TLP18.3 and Psb32 that have been implicated in the photosystem II (PSII) repair cycle. It may be involved in the regulation of synthesis/degradation of the D1 protein of the PSII core and in the assembly of PSII monomers into dimers in the grana stacks. In the model nematode C. elegans, the MOLO-1 protein is an auxiliary subunit that positively modulates the gating of levamisole-sensitive acetylcholine receptors. 1st Ca2+ coordination site. Water molecules sre shown as red spheres. 2nd Ca2+ coordination site in Antarctic bacterium protein BA42 (PDB code 4oa3).
