    text
  • mainly localized inside the nucleus
  • basic FUNCTION
  • involved in the basal expression of PAI1
  • binding the myosin light chain enhancer and likely, many other targets
  • required for error-free postreplication repair of damaged DNA (in keeping with its cancer-suppression role)
  • actin-dependent regulator of chromatin structure
  • promotes PCNA polyubiquitination
  • playing a role in promoting RAD6A/RAD18- and UBE2V2-UE2N-dependent PCNA polyubiquitination (implicates its involvement in promoting error-free postreplication repair through DNA lesions)
  • can facilitate fork regression and has a role in replication of damaged DNA
  • promotes the restart of replication forks blocked at DNA lesions and can promote error-free replication of damaged DNA
  • may be preventing mutagenesis and carcinogenesis
  • modulates basal expression of SERPINE1 involved in regulation of cell migration
  • HLTF and SHPRH suppress mutagenesis in a damage-specific manner
  • HLTF and SHPRH may coordinate the two main branches of postreplication repair to choose the proper bypass mechanism for minimizing mutagenesis
  • exhibits ubiquitin ligase activity for proliferating cell nuclear antigen (PCNA) polyubiquitylation as well as double-stranded DNA translocase activity for remodeling stalled replication fork by fork reversal
  • has an ATP hydrolysis-dependent protein remodeling activity, by which it can remove proteins bound to the replication fork
  • crucial role for SMARCA3 in S100A10-dependent neurogenic and behavioral response to chronic antidepressant administration
  • is involved in a RAD51-independent D-loop branch of template switch pathway that can promote repair of gaps formed during replication of damaged DNA
  • regulates transcription, remodels chromatin, and coordinates DNA damage repair
  • regulates G2/M transition, WT1/GATA4/HIF1A cardiac transcription networks, and collagen biogenesis
  • CELLULAR PROCESS nucleotide, chromatin organization
    nucleotide, transcription, regulation
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
  • S100A10/ANXA2/HLTF pathway mediates both neurogenic and behavioral responses to selective serotonin reuptake inhibitors (SSRIs)
  • a component
  • component of chromatin remodeling complexes
  • part of USP7-HLTF-PCNA molecular network controlling DNA damage response
  • INTERACTION
    DNA binding
    RNA
    small molecule
    protein
  • actin
  • ATP11B
  • CHFR-interacting protein
  • interact with a RING-finger binding protein (RFBP), which is a splice variant of the Type IV P-type ATPase, ATP11B
  • PAXIP1 and RPA1, both involved in DNA replication and DNA repair, are HLTF-interacting proteins although cells depleted of HLTF did not show defects in cellular responses to DNA damage
  • promotes the Lys-63-linked polyubiquitination of proliferating cell nuclear antigen (PCNA) that is required for maintaining genomic stability
  • USP7 is a novel regulator of HLTF stability
  • HLTF, chromatin-remodeling factor, is a target for the S100A10/ANXA2 heterotetrameric complex
  • S100A10/ANXA2 not only increases the DNA-binding affinity of HLTF but also anchors HLTF to the nuclear matrix presumably via the interaction of ANXA2 with actin and PIP2
  • cell & other
  • binding to the HIV long terminal repeat
