forkhead associated (FHA) domain found in protein phosphatase 1 regulatory inhibitor subunit 8 (PPP1R8) and similar proteins; PPP1R8, also called nuclear inhibitor of protein phosphatase 1 (NIPP-1), is an inhibitor subunit of the major nuclear protein phosphatase-1 (PP-1). It has RNA-binding activity but does not cleave RNA and may target PP-1 to RNA-associated substrates. It may also be involved in pre-mRNA splicing and binds DNA and might act as a transcriptional repressor. PPP1R8 seems to be required for cell proliferation. PPP1R8 contains an FHA domain that mediates interactions with threonine-phosphorylated maternal embryonic leucine zipper kinase (MELK). The FHA domain is a small phosphopeptide recognition module.

forkhead associated (FHA) domain found in Smad nuclear-interacting protein 1 (SNIP1), FHA domain-containing protein DDL, and similar proteins; SNIP1 is an FHA domain-containing protein required for pre-mRNA splicing as a component of the spliceosome. It inhibits NF-kappaB signaling by competing for its binding to the C/H1 domain of CBP/p300 transcriptional co-activators. It is involved in microRNA (miRNA) biogenesis. SNIP1 is a regulator of the cell cycle and cyclin D1 expression and may be involved in cyclin-D1/CCND1 mRNA stability through the SNARP complex which associates with both the 3'end of the CCND1 gene and its mRNA. This family also includes Arabidopsis thaliana FHA domain-containing protein DDL and similar proteins. DDL, also called protein DAWDLE, is involved in the microRNA (miRNA) and short interfering RNA (siRNA) biogenesis. It may facilitate DCL1 to access or recognize primary miRNAs. DDL binds RNA non-specifically. The FHA domain is a small phosphopeptide recognition module.

forkhead associated (FHA) domain found in transcription factor 19 (TCF-19) and similar proteins; TCF-19, also called transcription factor SC1, was identified as a putative trans-activating factor with expression beginning at the late G1-S boundary in dividing cells. It also functions as a novel islet factor necessary for proliferation and survival in the INS-1 beta cell line. It plays an important role in susceptibility to both Type 1 Diabetes Mellitus (T1DM) and Type 2 Diabetes Mellitus (T2DM); it has been suggested that it may positively impact beta cell mass under conditions of beta cell stress and increased insulin demand. TCF-19 contains an N-terminal fork head association domain (FHA), a proline rich region, and a C-terminal plant homeodomain (PHD) finger. The FHA domain may serve as a nuclear signaling domain or as a phosphoprotein binding domain. The proline rich region is a common characteristic of trans-activating factors. The PHD finger may allow TCF-19 to interact with chromatin via methylated histone H3.

forkhead associated (FHA) domain found in nibrin and similar proteins; Nibrin (NBN), also called cell cycle regulatory protein p95, or Nijmegen breakage syndrome protein 1 (NBS1), is a novel DNA double-strand break repair protein that is mutated in Nijmegen breakage syndrome. It is a component of the MRE11-RAD50-NBN (MRN complex) which plays a critical role in the cellular response to DNA damage and the maintenance of chromosome integrity. Nibrin modulates the DNA damage signal sensing by recruiting PI3/PI4-kinase family members ATM, ATR, and probably DNA-dependent protein kinase catalytic subunit (DNA-PKcs) to the DNA damage sites and activating their functions. It can also recruit MRE11 and RAD50 to the proximity of DSBs by an interaction with the histone H2AX. Nibrin also functions in telomere length maintenance by generating the 3' overhang which serves as a primer for telomerase dependent telomere elongation. Nibrin is a major player in the control of intra-S-phase checkpoint. This subfamily also includes Schizosaccharomyces pombe DNA repair and telomere maintenance protein Nbs1 and Arabidopsis thaliana AtNbs1. SpNbs1 is an FHA domain-containing protein required for DNA damage repair and S-phase DNA damage checkpoint. It is involved in telomere length maintenance and maintenance of chromatin structure. AtNbs1 is a component of MRN complex. It also functions in the very early stages of meiosis. The FHA domain is a small phosphopeptide recognition module.
