The Catsper2 Polyclonal Antibody (PACO39034) is a powerful tool for researchers studying the Catsper2 protein, which is essential for sperm function and male fertility. This antibody, produced in rabbits, exhibits high reactivity with human samples and has been validated for use in Western blot applications. By targeting the Catsper2 protein, this antibody allows for precise detection and analysis in a variety of cell types, making it ideal for investigations in reproductive biology and infertility research.Catsper2, a critical component of the Catsper ion channel complex, is involved in regulating calcium influx in sperm cells, which is essential for sperm motility and fertilization.
Dysfunction of Catsper2 has been implicated in male infertility and may be a target for developing novel fertility treatments. Research on Catsper2 is crucial for advancing our understanding of male reproductive health and developing strategies to address infertility issues in men.Overall, the Catsper2 Polyclonal Antibody (PACO39034) offers researchers a reliable tool for studying the role of Catsper2 in male fertility and reproductive biology, with the potential to contribute to advancements in the field of assisted reproductive technologies and infertility treatments.

Background:
Voltage-gated calcium channel that plays a central role in calcium-dependent physiological responses essential for successful fertilization, such as sperm hyperactivation, acrosome reaction and chemotaxis towards the oocyte. Activated by extracellular progesterone and prostaglandins following the sequence: progesterone > PGF1-α = PGE1 > PGA1 > PGE2 >> PGD2. The primary effect of progesterone activation is to shift voltage dependence towards more physiological, negative membrane potentials; it is not mediated by metabotropic receptors and second messengers. Sperm capacitation enhances the effect of progesterone by providing additional negative shift. Also activated by the elevation of intracellular pH.

Defects in CATSPER2 are a cause of deafness-infertility syndrome (DIS). DIS is characterized by deafness and infertility and is caused by large contiguous gene deletions at 15q15.3 that removes both STRC and CATSPER2 genes. Belongs to the cation channel sperm-associated (TC 1.A.1.19) family. 4 isoforms of the human protein are produced by alternative splicing.Protein type: Membrane protein, multi-pass; Membrane protein, integralChromosomal Location of Human Ortholog: 15q15.3Cellular Component: plasma membraneMolecular Function: protein binding; voltage-gated calcium channel activityBiological Process: response to progesterone stimulus; sperm motility; sperm-egg recognitionDisease: Deafness, Sensorineural, And Male Infertility; Spermatogenic Failure 7

NCBI Summary:
Calcium ions play a primary role in the regulation of sperm motility. This gene belongs to a family of putative cation channels that are specific to spermatozoa and localize to the flagellum. The protein family features a single repeat with six membrane-spanning segments and a predicted calcium-selective pore region. This gene is part of a tandem repeat on chromosome 15q15; the second copy of this gene is thought to be a pseudogene. Alternatively spliced transcript variants have been found for this gene.
