| Short Name | MAT1-1-2/MatA-2/Smr1 |
| description | This entry includes MAT1-1-2, MatA-2 and Smr1 from Sordariomycetes. MatA-2 is encoded by the MAT1-1-2 gene which is present in the mating types of Sordariomycetes. The most famous representative in this class of fungi is Neurospora crassa. MAT1-1-2 is the generic nomenclature of all mating-type genes encoding proteins with a HPG (also termed PPF) domain. This gene and its domain was first identified in Podospora anserina (its name in this species is Smr1) and Neurospora crassa (its name in this species is MatA-2) []. HPG was the first name proposed for the domain found in MAT1-1-2 proteins see [], based on the most conserved residues (histidine, proline and glycine). PPF was a second denomination []for the same domain but these authors identified different conserved residues (proline, proline and phenylalanine).Smr1 from Podospora anserina contains a putative acidic/hydrophobic α-helix, which has been proposed to be a feature common to transcriptional activators []. |
