Summaries for DAZ4 Gene

Entrez Gene Summary for DAZ4 Gene

  • This gene is a member of the DAZ gene family and is a candidate for the human Y-chromosomal azoospermia factor (AZF). Its expression is restricted to premeiotic germ cells, particularly in spermatogonia. It encodes an RNA-binding protein that is important for spermatogenesis. Four copies of this gene are found on chromosome Y within palindromic duplications; one pair of genes is part of the P2 palindrome and the second pair is part of the P1 palindrome. Each gene contains a 2.4 kb repeat including a 72-bp exon, called the DAZ repeat; the number of DAZ repeats is variable and there are several variations in the sequence of the DAZ repeat. Each copy of the gene also contains a 10.8 kb region that may be amplified; this region includes five exons that encode an RNA recognition motif (RRM) domain. This gene contains two copies of the 10.8 kb repeat. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Feb 2011]

    Protein attributes for DAZ4 Gene

    579 amino acids
    Molecular mass:
    64785 Da
    Quaternary structure:
    • Forms a heterodimer with BOLL and DAZL. Interacts with PUM2, DAZAP1, DAZAP2, DZIP1 and DZIP3.
    • DAZ genes are prone to deletions but also to duplications. In a population of infertile men, DAZ genes deletions are associated with oligozoospermia but an increased number of DAZ genes is not a significant risk factor for spermatogenic failure
    • The DAZ proteins (DAZ, DAZ2, DAZ4 and DAZ4) are all encoded by a strongly repeated region of the Y chromosome, in two clusters each comprising an inverted pair of DAZ genes. They are very similar, which gives their indidual characterization difficult. Thus, most experiments do not discriminate between the different members. One can therefore suppose that reported interactions with a DAZ protein involve all the 4 proteins
