Family: Raptor_N (PF14538)

Summary: Raptor N-terminal CASPase like domain

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.

Raptor N-terminal CASPase like domain Provide feedback

This domain is found at the N-terminus of the Raptor protein. It has been identified to have a CASPase like structure [1]. It conserves the characteristic cys/his dyad of the caspases suggesting it may have a peptidase activity.

InterPro entry IPR029347

Human Raptor is involved in the control of the mammalian target of rapamycin complex 1 (mTORC1) activity which regulates cell growth and survival, and autophagy in response to nutrient and hormonal signals. It functions as a scaffold for recruiting mTORC1 substrates [PUBMED:12150925].

All Raptor orthologs contain a unique conserved region in their N-terminal half (raptor N-terminal conserved, also called the RNC domain) followed by three HEAT (huntingtin, elongation factor 3, A subunit of protein phosphatase 2A and TOR1) repeats and seven WD-40 repeats near the C terminus [PUBMED:12150925, PUBMED:12150926].

This entry reprsents the RNC domain, which consists of 3 blocks with at least 67 to 79% sequence similarity and is predicted to have a high propensity to form alpha helices. The RNC domain is characterised by the presence of invariant catalytic Cys-His dyad, which is structurally and evolutionarily related to known caspases, suggesting that the raptor proteins may have protease activity [PUBMED:15450605].

Pfam Clan

This family is a member of clan Peptidase_CD (CL0093), which has the following description:

The members of this clan are all endopeptidase that have the catalytic dyad histidine followed by cysteine. The catalytic histidine is preceded by a block of hydrophobic residues and a glycine, where as the cysteine is preceded by a block of hydrophobic residues and a glutamine and an alanine. The members with a know structure adopt an alpha/beta fold [1].

The clan contains the following 9 members:

CHAT GVQW Peptidase_C11 Peptidase_C13 Peptidase_C14 Peptidase_C25 Peptidase_C50 Peptidase_C80 Raptor_N

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.

HMM logo

HMM logos is one way of visualising profile HMMs. Logos provide a quick overview of the properties of an HMM in a graphical form. You can see a more detailed description of HMM logos and find out how you can interpret them here. More...

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.
