Characterization and expression profile of CMTM3/CKLFSF3

Area of Science:

• Molecular Biology
• Immunology
• Reproductive Biology

Background:

• The CMTM/CKLFSF family comprises nine human genes encoding proteins that link chemokines and TM4SF.
• Understanding the specific roles of individual CMTM/CKLFSF family members is crucial for elucidating their biological functions.

Purpose of the Study:

• To characterize the human CMTM3/CKLFSF3 gene and its protein expression profile.
• To investigate the evolutionary conservation and potential physiological roles of CMTM3/CKLFSF3.

Main Methods:

• RT-PCR and Quantitative Real-time PCR were employed to assess gene transcription levels.
• A polyclonal antibody was generated to detect CMTM3/CKLFSF3 protein expression.
• Protein expression was analyzed in various human tissues and peripheral blood mononuclear cells (PBMCs).

Main Results:

• Human CMTM3/CKLFSF3 exhibits high sequence identity with its mouse and rat homologues, indicating evolutionary conservation.
• CMTM3/CKLFSF3 gene transcription is significantly high in the testis, leukocytes, and spleen.
• CMTM3/CKLFSF3 protein is highly expressed in the testis and certain PBMC populations.

Conclusions:

• CMTM3/CKLFSF3 is an evolutionarily conserved gene with a distinct expression pattern.
• The expression profile suggests potential important roles for CMTM3/CKLFSF3 in the male reproductive and immune systems.
• Further research is warranted to elucidate the specific functions of CMTM3/CKLFSF3 in these systems.
