An Activin receptor is a receptor which binds activin.

Types include:

These proteins are receptor-type kinases of Ser/Thr type, which have a single transmembrane domain and a specific hydrophilic Cys-rich ligand-binding domain.[1][2][3]

Activin types I and II receptor domain Provide feedback

This Pfam entry consists of both TGF-beta receptor types. This is an alignment of the hydrophilic cysteine-rich ligand-binding domains, Both receptor types, (type I and II) posses a 9 amino acid cysteine box, with the the consensus CCX{4-5}CN. The type I receptors also possess 7 extracellular residues preceding the cysteine box.

InterPro entry IPR000472

Transforming growth factor-beta (TGF-beta) forms a family with other growth factors described in PROSITEDOC. The receptors for most of the members of this growth factor family are related. These proteins are receptor-type kinases of Ser/Thr type PROSITEDOC), which have a single transmembrane domain and a specific hydrophilic Cys-rich ligand-binding domain [PUBMED:9023056, PUBMED:8047140, PUBMED:8909794]. The C-terminal part of the extracellular domain is conserved. Some of the receptors of this family contain subclass-specific N-terminal extensions of this homology domain. The type I receptors also possess 7 extracellular residues preceding the cysteine box.

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 using the family HMM. We also generate alignments using four representative proteomes (RP) sets, the NCBI sequence database, and our metagenomics 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.

MyHits provides a collection of tools to handle multiple sequence alignments. For example, one can refine a seed alignment (sequence addition or removal, re-alignment or manual edition) and then search databases for remote homologs using HMMER3.

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 Activin_recp domain has been found. There are 67 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.
