Abstract This family includes the yeast ASF1 protein, which derepresses transcriptionally silenced genes. The human ASF1 homologue has been found to possess histone chaperone activity, which may explain the derepressing function of this family [PubMed10759893].

The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level. Click on the 'Genome Assignments' icon above to view the genome assignments for this superfamily.


Alignments of sequences to

Alignments of sequences to 1 models in this superfamily are available by clicking on the superfamily level 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequences may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own.


It is possible to browse and view the proteins in the genomes which have different combinations of domains including a ASF1-like domain. Click on the 'Domain Combinations' icon.


To view the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom click on the 'TaxViz' icon above. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Undirected domain occurrence networks are available for all superfamilies. Nodes in these networks represent genomes. Connections between nodes represent the presence of domain architectures, which contain the superfamily of interest, in both genomes.

There are 1 hidden Markov models representing the ASF1-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be viewed by clicking on the icon above.
