CFAP157 gene is "specifically required during spermatogenesis for flagellum morphogenesis and sperm motility and may be required to suppress the formation of supernumerary axonemes and ensure a correct ultrastructure,"[5] according to UniProt.

Gene

Location

CFAP157 is located on chromosome 9, 9q34.11 in human from base pair 127,706,989 to base pair 127,716,002.[6]

Location of CFAP157 in chromosome 9

Features

The size of the gene is 9,013 bases, and the orientation is plus strand.[6] The gene holds 9 exons.[7]

mRNA

The most common variant of mRNAs of CFAP157 contains 1,722 base pairs.[7]

Expression

CFAP157 is expressed in many human body tissues such as cervix, lung, testis, and uterus. People who have uterine tumor are likely to have an expression in CFAP157. This gene is expressed in both adults and fetuses.[8]

Protein

There are 520 amino acids in CFAP157 in human.[9] The protein is glutamine extremely rich, and glycine poor. The protein is quite neutral with the isoelectric point at pH 7.4.[10] The average mass of the protein is estimated to be 60,531.748 Da, and the absorption coefficient is estimated to be 25,440 M−1 cm−1.

CFAP157 is primarily composed of α-helices, and there is no transmembrane helix. The protein structure making program called Phyre is used to create the predicted structure of CFAP157.

Interacting Proteins

P14335 (Kunjin virus strain MRM61C) is the virus that interacts with CFAP157 via two-hybrid screening. Kunjin virus is not as severe as other viruses, but this is a noticeable discovery because it is possible to exploit the interaction to develop new types of medicine. Researchers at the University of Queensland discovered a new medical use for the Kunjin virus in 2005, and the possible treatments include HIV/cancer vaccines.[12]
