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 have been implicated the photosystem II (PSII) repair cycle.
