Powering down the Pfam website
On October 5th, we will start redirecting the traffic from Pfam (pfam.xfam.org) to InterPro (www.ebi.ac.uk/interpro). The Pfam website will be available at pfam-legacy.xfam.org until January 2023, when it will be decommissioned. You can read more about the sunset period in our blog post.

Family: Ephrin_rec_like (PF07699)

Summary: Tyrosine-protein kinase ephrin type A/B receptor-like

Pfam includes annotations and additional family information from a range of different sources. These sources can be accessed via the tabs below.

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.

Tyrosine-protein kinase ephrin type A/B receptor-like Provide feedback

InterPro entry IPR011641

Protein phosphorylation, which plays a key role in most cellular activities, is a reversible process mediated by protein kinases and phosphoprotein phosphatases. Protein kinases catalyse the transfer of the gamma phosphate from nucleotide triphosphates (often ATP) to one or more amino acid residues in a protein substrate side chain, resulting in a conformational change affecting protein function. Phosphoprotein phosphatases catalyse the reverse process. Protein kinases fall into three broad classes, characterised with respect to substrate specificity [ PUBMED:3291115 ]:

  • Serine/threonine-protein kinases
  • Tyrosine-protein kinases
  • Dual specificity protein kinases (e.g. MEK - phosphorylates both Thr and Tyr on target proteins)

Protein kinase function is evolutionarily conserved from Escherichia coli to human [ PUBMED:12471243 ]. Protein kinases play a role in a multitude of cellular processes, including division, proliferation, apoptosis, and differentiation [ PUBMED:12368087 ]. Phosphorylation usually results in a functional change of the target protein by changing enzyme activity, cellular location, or association with other proteins. The catalytic subunits of protein kinases are highly conserved, and several structures have been solved [ PUBMED:15078142 ], leading to large screens to develop kinase-specific inhibitors for the treatments of a number of diseases [ PUBMED:15320712 ].

This entry represents a domain found in various ephrin type A and B receptors, which have tyrosine kinase activity.

Tyrosine-protein kinases can transfer a phosphate group from ATP to a tyrosine residue in a protein. These enzymes can be divided into two main groups [ PUBMED:12471243 ]:

  • Receptor tyrosine kinases (RTK), which are transmembrane proteins involved in signal transduction; they play key roles in growth, differentiation, metabolism, adhesion, motility, death and oncogenesis [ PUBMED:19275641 ]. RTKs are composed of 3 domains: an extracellular domain (binds ligand), a transmembrane (TM) domain, and an intracellular catalytic domain (phosphorylates substrate). The TM domain plays an important role in the dimerisation process necessary for signal transduction [ PUBMED:16700535 ].

  • Cytoplasmic / non-receptor tyrosine kinases, which act as regulatory proteins, playing key roles in cell differentiation, motility, proliferation, and survival. For example, the Src-family of protein-tyrosine kinases [ PUBMED:15845350 ].

Pfam Clan

This family is a member of clan EGF (CL0001), which has the following description:

Members of this clan all belong to the EGF superfamily. This particular superfamily is characterised as having least 6 cysteine residues. These cysteines form disulphide bonds, in the order 1-3, 2-4, 5-6, which are essential for the stability of the EGF fold. These disulphide bonds are stacked in a ladder-like arrangement. The Laminin EGF family is distinguished by having an an additional disulphide bond. The function of the domains within this family remains unclear, but they are thought to largely perform a structural role. More often than not, these domains are arranged in tandem repeats in extracellular proteins.

The clan contains the following 22 members:

Alignments

We store a range of different sequence alignments for families. As well as the seed alignment from which the family is built, we provide the full alignment, generated by searching the sequence database (reference proteomes) using the family HMM. We also generate alignments using four representative proteomes (RP) sets and the UniProtKB sequence database. More...

View options

We make a range of alignments for each Pfam-A family. You can see a description of each above. You can view these alignments in various ways but please note that some types of alignment are never generated while others may not be available for all families, most commonly because the alignments are too large to handle.

Trees

This page displays the phylogenetic tree for this family's seed alignment. We use FastTree to calculate neighbour join trees with a local bootstrap based on 100 resamples (shown next to the tree nodes). FastTree calculates approximately-maximum-likelihood phylogenetic trees from our seed alignment.

Note: You can also download the data file for the tree.

Structures

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 Ephrin_rec_like domain has been found. There are 3 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 sequence.
