Recombinant Human 39S ribosomal protein L41, mitochondrial (MRPL41)

Uniprot Id

Q8IXM3

Target Species

Human

Target Name

MRPL41

Target Full Name

Large ribosomal subunit protein mL41

Target Function

Component of the mitochondrial ribosome large subunit. Also involved in apoptosis and cell cycle. Enhances p53/TP53 stability, thereby contributing to p53/TP53-induced apoptosis in response to growth-inhibitory condition. Enhances p53/TP53 translocation to the mitochondria. Has the ability to arrest the cell cycle at the G1 phase, possibly by stabilizing the CDKN1A and CDKN1B (p27Kip1) proteins.

Target Subcellular Location

Mitochondrion.

Target Protein Families

Mitochondrion-specific ribosomal protein mL41 family

Target Tissue Specificity

Present in kidney, liver, thymus and testis, and at lower level in brain and spleen (at protein level).

Target Background

Mammalian mitochondrial ribosomal proteins are encoded by nuclear genes and help in protein synthesis within the mitochondrion. Mitochondrial ribosomes (mitoribosomes) consist of a small 28S subunit and a large 39S subunit. They have an estimated 75% protein to rRNA composition compared to prokaryotic ribosomes, where this ratio is reversed. Another difference between mammalian mitoribosomes and prokaryotic ribosomes is that the latter contain a 5S rRNA. Among different species, the proteins comprising the mitoribosome differ greatly in sequence, and sometimes in biochemical properties, which prevents easy recognition by sequence homology. This gene encodes a 39S subunit protein that belongs to the YmL27 ribosomal protein family.
