Anti-HDAC8 Antibody Picoband®

HDAC8, Histone deacetylase 8, is an enzyme that in humans is encoded by the HDAC8 gene, and is biologically involved in skull morphogenesis and metabolic control of the ERR-alpha/PGC1-alpha transcriptional complex. Sequence analysis predicted that the 377-amino acid HDAC8 protein contains the 9 conserved HDAC blocks that are presumably important for catalytic function. HDAC8 shares 54% sequence similarity with HDAC1 and HDAC2 and 39% similarity with HDAC3, making it a class I HDAC. Histones play a critical role in transcriptional regulation, cell cycle progression, and developmental events. Histone acetylation/deacetylation alters chromosome structure and affects transcription factor access to DNA. The protein encoded by this gene belongs to class I of the histone deacetylase/acuc/apha family. It has histone deacetylase activity and represses transcription when tethered to a promoter.

May be involved in follicular development. Oocyte-specific growth/differentiation factor that stimulates folliculogenesis and granulosa cell (GC) growth. The mature protein migrates in two distinct mature proteins, P16 (16KDa) and P17 (17KDa) . Ovarian physiology and fertility are controlled by endocrine and paracrine signals. These act in a species-dependent manner and determine the ovulation quota in different mammalian species. While humans, and mammals such as the cow or red deer, normally ovulate only one egg per cycle, other mammals such as mouse and pig can ovulate in excess of ten per cycle. The mechanisms that regulate the species-specific differences in the number of follicles that go onto ovulate during each reproductive cycle are poorly understood. According to PubMed:21970812, mRNA expression levels of GDF9 and BMP15 are tightly coregulated within each species and influence species-specific ovulation-rates.
