General Information

Paragraph No	Gene Name	Paragraph Text
12	THD1	THD1, a homolog of the Saccharomyces cerevisiae Rpd3p, a class I histone deacetylase (HDAC), is localized to the macronucleus during vegetative growth, and distributed to developing new macronuclei early in their differentiation. Thd1p deacetylates all four core histones in vitro. Thd1p is a 52kDa polypeptide in an HDAC complex of approximately 160 kDa.
13	THD1	Tetrahymena cells with reduced Thd1p expression exhibited phenotypes indicative of loss of chromatin integrity, such as DNA fragmentation and extrusion of chromatin from the macronucleus, variable macronuclear size and shape, enlarged nucleoli, and reduced phosphorylation of histone H1 from bulk chromatin. Macronuclei in THD1 knockdown cells also contained more DNA, suggesting Thd1p may play a role in regulating macronuclear DNA content. The THD1 gene could not be completely replaced by a disruption construct, suggesting that THD1 is an essential gene.
