Protein attributes

Sequence length	144 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Acts a component of the CCAT-binding factor, which is a transcriptional activator and binds to the upstream activation site (UAS2) of the CYC1 gene and other genes involved in mitochondrial electron transport and activates their expression. Recognizes the sequence 5'-CCAAT-3'.
Subunit structure	Component of the CCAT-binding factor (CBF or HAP complex II), which consists of one copy each of HAP2, HAP3, HAP4 and HAP5. The assembly of the HAP2-HAP3-HAP5 heteromer (HAP complex I) occurs in a one-step pathway and its binding to DNA is a prerequisite for the association of HAP4. Ref.7
Subcellular location	Nucleus.
Miscellaneous	Present with 2510 molecules/cell in log phase SD medium.
Sequence similarities	Belongs to the NFYB/HAP3 subunit family.
