产品介绍background:
ASF1a belongs to the H3/H4 family of histone chaperone proteins. The protein is a key component of a histone donor complex that functions in nucleosome assembly. It interacts with histones H3 and H4, and functions together with a chromatin assembly factor during DNA replication, repair and silencing.
Function:
Histone chaperone that facilitates histone deposition and histone exchange and removal during nucleosome assembly and disassembly. Cooperates with chromatin assembly factor 1 (CAF-1) to promote replication-dependent chromatin assembly and with HIRA to promote replication-independent chromatin assembly. Required for the formation of senescence-associated heterochromatin foci (SAHF) and efficient senescence-associated cell cycle exit.
Subunit:
Interacts with histone H3 (including both histone H3.1 and H3.3) and histone H4. Interacts with the CHAF1A, CHAF1B and RBBP4 subunits of the CAF-1 complex. Interacts with CABIN1, HAT1, HIRA, NASP, TAF1, TLK1, TLK2 and UBN1. Interacts with CDAN1. Found in a cytosolic complex with CDAN1, ASF1B, IPO4 and histones H3.1 and H4.
Subcellular Location:
Nucleus.
Tissue Specificity:
Ubiquitously expressed.
Post-translational modifications:
Phosphorylated by TLK1 and TLK2. Highly phosphorylated in S-phase and at lower levels in M-phase. TLK2-mediated phosphorylation at Ser-192 prevents proteasome-dependent degradation.
Similarity:
Belongs to the ASF1 family.

ASF1a能够促进细胞衰老并且是与衰老有关的细胞周期停滞所必须的。HIRA/ASF1a介导的SAHF的形成过程直接促进细胞脱离细胞周期循环进入衰老阶段。研究人员还推测HIRA和ASF1a的改变可能使细胞无法脱离细胞周期并可能导致癌症的发生。
