The present invention relates to a novel protein interacting with phytochromes and use thereof, and more particularly, to a polypeptide having either an amino acid sequence set forth in SEQ ID NO: 4 or an amino acid sequence having at least 70% with said amino acid sequence, and use thereof. The polypeptide interacts with phytochromes A and B, and the TPR domain present at the N-terminal region of the polypeptide is involved in the interaction. Also, a PP2A catalytic domain (PP2Ac) having phosphatase activity is present at the C-terminal region of the polypeptide. The polypeptide can be used as a phosphatase, and is useful in the production of plants sensitive to light signal transduction. Furthermore, the TPR domain present in the polypeptide is useful in the production of dwarf plants.

摘要:
A blood pressure meter using a viscoelastic cuff, and a mobile terminal having the blood pressure meter. The blood pressure meter includes a blood pressure sensor for measuring variation in blood pressure, a blood flow sensor for measuring variation in blood flow, a cuff that elastically compresses a body part and decompresses the body part due to its viscoelasticity, and a control unit that analyzes signals measured by the blood pressure sensor and the blood flow sensor and calculates blood pressure. The blood pressure meter is detachably connected to a mobile terminal body, and can be small and portable. It is possible to measure the blood pressure precisely even when the cuff is fitted onto a finger, thereby improving the reliability of the blood pressure measurement. By using the viscoelasticity of the cuff and auxiliary decompressing, it is possible to check the blood pressure at all times.
