Summary: Fumble
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.
Fumble Provide feedback
Fumble is required for cell division in Drosophila. Mutants lacking fumble exhibit abnormalities in bipolar spindle organisation, chromosome segregation, and contractile ring formation. Analyses have demonstrated that encodes three protein isoforms, all of which contain a domain with high similarity to the pantothenate kinases of A. nidulans and [1]. A role of fumble in membrane synthesis has been [1].

InterPro entry IPR004567
This family describes the type II form of pantothenate kinase PanK, characterised from the fungus Emericella nidulans and with similar forms known in several other eukaryotes. It also includes forms from several Gram-positive bacteria suggested to have originated from the eukaryotic form by lateral transfer. It differs in a number of biochemical properties (such as inhibition by acetyl-CoA) from type I PanK enzymes and shows little sequence similarity [ PUBMED:9890959 , PUBMED:12760898 ].
Pantothenate kinase (PanK or CoaA) catalyses the first step of the universal five step coenzyme A (CoA) biosynthesis pathway. CoA is a ubiquitous and essential cofactor in all living organsims. Pantothenate kinase catalyses the first and rate limiting step in the CoA biosynthetic pathway, which involves transferring a phosphoryl group from ATP to pantothenate, also known as vitamin B5. Three distinct types of pantothenate kinase enzymes have been identified: type I PanK enzymes are typified by the E. coli CoaA protein, type II enzymes are primarily found in eukaryotic organisms whilst type III enzymes have a wider phylogenic distribution and are not feedback inhibited by CoA [ PUBMED:18186650 ].

Pfam Clan
This family is a member of clan Actin_ATPase (CL0108), which has the following description:
The actin-like ATPase domain forms an alpha/beta canonical fold. The domain can be subdivided into 1A, 1B, 2A and 2B subdomains. Subdomains 1A and 1B share the same RNAseH-like fold (a five-stranded beta-sheet decorated by a number of alpha-helices). Domains 1A and 2A are conserved in all members of this superfamily, whereas domain 1B and 2B have a variable structure and are even missing from some homologues [1]. Within the actin-like ATPase domain the ATP-binding site is highly conserved. The phosphate part of the ATP is bound in a cleft between subdomains 1A and 2A, whereas the adenosine moiety is bound to residues from domains 2A and 2B[1].
The clan contains the following 34 members:

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.

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.

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 Fumble domain has been found. There are 64 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.
