The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
This tab holds the annotation information that is stored in the Pfam database. As we move to using Wikipedia as our main source of annotation, the contents of this tab will be gradually replaced by the Wikipedia tab.
Prolamin-like Provide feedback
Prolamin_like (in which DUF784 and DUF1278 have been merged) is found to be expressed in the plant embryo sac and to be regulated by the Myb98 transcription factor. Computational analysis has revealed that members are homologous to the plant prolamin superfamily (Protease inhibitor-seed storage-LTP family, PF00234) . In contrast to typical prolamin members that have eight conserved Cys residues forming four pairs of disulfide bonds, this domain contains only six conserved Cys residues that may form three pairs of disulfide bonds. The domain may have a potential function in lipid transfer or protection during plant embryo sac development and reproduction .

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
