The Clock gene
a key molecule in circadian systems
is widely distributed in the animal kingdom. We isolated a 936-bp partial cDNA sequence of the Clock gene (Pva-clock) from the darkbarbel catfish Pelteobagrus vachelli that exhibited high identity with Clock genes of other species of fish and animals (65%–88%). The putative domains included a basic helix-loop-helix (bHLH) domain and two period-ARNT-single-minded (PAS) domains
which were also similar to those in other species of fish and animals. Pva-Clock was primarily expressed in the brain
and was detected in all of the peripheral tissues sampled. Additionally
the pattern of Pva-Clock expression over a 24-h period exhibited a circadian rhythm in the brain
liver and intestine
with the acrophase at zeitgeber time 21:35
23:00
and 23:23
respectively. Our results provide insight into the function of the molecular Clock of P. vachelli.
