Annotated Information
Rad21/Rec8 is an important component and key regulator of cohesins. OsRAD21-4, a RAD21-like gene from rice Zhonghua 10 (Oryza sativa L. ssp.japonica), is a single-copy gene in the rice genome and essential for efficient meiosis.
Function
OsRad21-4 is a relatively hydrophilic protein and contains the entire Pfam04825 and Pfam04824 domains (spanning amino acids 1–115 and 554–608, respectively) (Figure 2A), of which Pfam04825 is highly conserved in all known members and Pfam04824 present in most of the Rad21/Rec8 family.[1,2] The two domain regions are spaced by a long linker sequence (amino acids 116-553). This linker sequence contains a potential nuclear targeting motif at positions 272–279 (KRKKRRKD), 2 separase recognition sites at 411–421 (ADDIEKLRGNT) and 420–430 (NTSGEYGRDYD) and a PEST motif at 511– 534 (RLSDVGPTPDLLEEIEPTQTPYEK) (Figure 2A). These motifs are proposed to be implicated in function regulation in cohesion establishment and disassociation [1,3]. In rice, OsRad21-4 is required for homologous pairing and segregation. It might be responsible mainly for sister chromatid-arm cohesion and to a lesser extent or not at all for centromere cohesion. In addition, OsRad21-4 is required for chromosome condensation. OsRad21-4 was essential to meiosis.
Expression
OsRad21-4 is present in the rice genome as a single-copy gene. The mRNA and protein of OsRad21-4 were expressed preferentially in young flowers where the pollen mother cells (PMCs) were in pre-meiotic stages. OsRAD21-4 cDNA cloned here is 2133 bp long and has a 5' UTR of 54 bp, a 3' UTR of 255 bp and an ORF of 1824 bp encoding a deduced polypeptide of 608 amino acids (OsRad21-4). OsRad21-4 has a calculated molecular mass of 68.5 kDa and an isoelectric point (pI) of 5.45. The protein is a nucleus-localizing protein.(Figure 2B) As shown in Figure 3A, OsRad21-4 was expressed preferentially in flowers, weakly in leaves and barely in buds and roots. Furthermore, OsRad214 was expressed dominantly just before the premeiotic stage of PMCs. (Figure 3C) This gene should function in premeiotic and meiotic PMCs, which is consistent with this notion that meiotic cohesion is established at the pre-meiotic S phase.
