ANGEL NUMBER 424
Number 424 is a compilation of the energies and attributes of number 4 and number 2, with number 4 appearing twice, amplifying its influences. Number 4 resonates with patience, practicality and application, hard work and responsibility, traditional values, honesty and integrity, innerwisdom, and diligence and determination to achieve goals. Number 4 also relates to our drive, passion and purpose, and the energies of the Archangels. Number 2 carries the vibrations of duality, partnership and relationships, diplomacy and adaptability, sensitivity and selflessness, happiness and fulfilment. Number 2 also resonates with faith and trust and your Divine life purpose and soul mission.

Catechism of the Catholic Church
460 The Word became flesh to make us "partakers of the divine nature":"For this is why the Word became man, and the Son of God became the Son of man: so that man, by entering into communion with the Word and thus receiving divine sonship, might become a son of God." "For the Son of God became man so that we might become God." "The onlybegotten Son of God, wanting to make us sharers in his divinity, assumed our nature, so that he, made man, might make men gods."

A Gene ID.
This gene encodes one of the SERCA Ca(2+)ATPases, which are intracellular pumps located in the sarcoplasmic or endoplasmic reticula of muscle cells. This enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol into the sarcoplasmic reticulum lumen, and is involved in regulation of the contraction/relaxation cycle. Mutations in this gene cause DarierWhite disease, also known as keratosis follicularis, an autosomal dominant skin disorder characterized by loss of adhesion between epidermal cells and abnormal keratinization. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2008]
