Domain of unknown function (DUF4091). This presumed domain is functionally uncharacterized. This domain family is found in bacteria, archaea and eukaryotes, and is approximately 70 amino acids in length. There is a single completely conserved residue G that may be functionally important.

Bacterial Ig-like domain (group 2). This family consists of bacterial domains with an Ig-like fold. Members of this family are found in bacterial and phage surface proteins such as intimins.

Uncharacterized conserved protein YjdB, contains Ig-like domain [General function prediction only].

FIVAR domain. This domain is found in a wide variety of contexts, but mostly occurring in cell wall associated proteins. A lack of conserved catalytic residues suggests that it is a binding domain. From context, possible substrates are hyaluronate or fibronectin (personal obs: C Yeats). This is further evidenced by. Possibly the exact substrate is N-acetyl glucosamine. Finding it in the same protein as pfam05089 further supports this proposal. It is found in the C-terminal part of Bacillus sp. Gellan lyase, which is removed during maturation. Some of the proteins it is found in are involved in methicillin resistance. The name FIVAR derives from Found In Various Architectures.

Fibronectin type 3 domain; One of three types of internal repeats found in the plasma protein fibronectin. Its tenth fibronectin type III repeat contains an RGD cell recognition sequence in a flexible loop between 2 strands. Approximately 2% of all animal proteins contain the FN3 repeat; including extracellular and intracellular proteins, membrane spanning cytokine receptors, growth hormone receptors, tyrosine phosphatase receptors, and adhesion molecules. FN3-like domains are also found in bacterial glycosyl hydrolases.
