Prolamin-like Provide feedback
Both DUF784 and DUF1278 members are found to be expressed in the plant embryo sac and are regulated by the Myb98 transcription factor. Computational analysis has revealed that they are homologous to the plant prolamin superfamily (Protease inhibitor-seed storage-LTP family, PF00234) . In contrast to the typical prolamin members that have eight conserved Cys residues forming four pairs of disulfide bonds, both DUF784 and DUF1278 domains only contain six conserved Cys residues that may form three pairs of disulfide bonds. These two domains may have potential functions in lipid transfer or protection during plant embryo sac development and reproduction . This family has been merged with the DUF1278 family.

Proteins with this domain are are found to be expressed in the plant embryo sac and are regulated by the Myb98 transcription factor. Computational analysis has revealed that they are homologous to the plant prolamin superfamily (Protease inhibitor-seed storage-LTP family, ) [PUBMED:19806031]. In contrast to the typical prolamin members that have eight conserved Cys residues forming four pairs of disulphide bonds, proteins with this domain only contain six conserved Cys residues that may form three pairs of disulphide bonds. They may have potential functions in lipid transfer or protection during plant embryo sac development and reproduction [PUBMED:17937500]. This domain includes both previous DUF784 and DUF1278 domains.

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request
