Summary: Switch protein XOL-1, GHMP-like
Switch protein XOL-1, GHMP-like Provide feedback
Members of this family, which are required for the formation of the active site of the sex-determining protein Xol-1, adopt a secondary structure consisting of five alpha helices and seven antiparallel beta sheets, in a beta-alpha-beta-alpha-alpha-alpha-beta-beta-alpha-beta-beta-beta arrangement. The fold of this family is structurally similar to that found in the C-terminal domain of GHMP Kinase .
Luz JG, Hassig CA, Pickle C, Godzik A, Meyer BJ, Wilson IA; , Genes Dev. 2003;17:977-990.: XOL-1, primary determinant of sexual fate in C. elegans, is a GHMP kinase family member and a structural prototype for a class of developmental regulators. PUBMED:12672694 EPMC:12672694

This domain, found in sex-determining protein Xol-1, adopts a secondary structure consisting of five alpha helices and seven antiparallel beta sheets, in a beta-alpha-beta-alpha-alpha-alpha-beta-beta-alpha-beta-beta-beta arrangement. The fold of this family is structurally similar to that found in the C-terminal domain of GHMP Kinase [PUBMED:12672694]. The active site of the enzyme is found at the interface between this domain and the N-terminal domain.

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

You can use the tree controls to manipulate how the interactive tree is displayed:
- show/hide the summary boxes
- highlight species that are represented in the seed alignment
- expand/collapse the tree or expand it to a given depth
- select a sub-tree or a set of species within the tree and view them graphically or as an alignment
- save a plain text representation of the tree
There are 2 interactions for this family. More...
We determine these interactions using iPfam, which considers the interactions between residues in three-dimensional protein structures and maps those interactions back to Pfam families. You can find more information about the iPfam algorithm in the journal article that accompanies the website.
For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the Xol-1_GHMP-like domain has been found. There are 2 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
