Annotated Information
The gene CAP1 is a highly conserved plant-specific gene that encode an arabinokinase-like protein which is critical for pollen development in both monocotyledonous and dicotyledonous plants.
Function
The gene Os02g0141300 locates at chromosome 2 and is composed of 28 exons that encode a protein of 996 amino acids. It appears to be a member of the galactokinase, homo-Ser kinase, mevalonate kinase, and phosphomevalonate kinase (GHMP) superfamily. The N-terminal half of CAP1 contained a glycosyltransferase family 1 domain (30–338 amino acids), while the C-terminal half contained both a Gal-binding (GB) signature (496–540 amino acids) and a GHMP N-terminal (GHMP-N) domain (638–704 amino acids). The GHMP-N domain is involved in ATP binding (Tsay and Robinson, 1991;Lee and Leustek, 1999).
The protein encoded by CAP1 shows high similarity to Arabidopsis (Arabidopsis thaliana) l-arabinokinase, which catalyzes the conversion of l-arabinose to l-arabinose 1-phosphate. This indicates that CAP1 is a arabinokinase-like protein.

Evolution
A closely related protein, Os06g0702500, is also found in the rice genome. It encodes a protein with 79% identity to CAP1 and is termed OsARA1.
Similar proteins are found in many higher plants, including Gramineae and Arabidopsis (between 90% and 71% identity), the fern Selaginella moellendorffii (67%), and the moss Physcomitrella patens (63%).
In Gramineae, there are at least two similar proteins in a genome that are divided into two phylogenetically distinct clades, the CAP1 clade (with about 90% identity to CAP1) and the OsARA1 clade (about 80% identity).
The Arabidopsis genome also contains two genes similar to CAP1; AtARA1 (At4g16130) has 75% identity to CAP1 and encods an arabinokinase (Dolezal and Cobbett, 1991; Gy et al., 1998; Sherson et al., 1999), and AtARA2, has 71% identity.
No highly homologous proteins are found in bacteria or animal genomes, which suggests that CAP1is a highly conserved plant-specific gene whose product appears to act as an arabinokinase.
