The ability of RTKs to dimerize is dependent on their phosphorylation status. Phosphorylation of specific tyrosine residues on the RTK allows for dimerization and subsequent activation of downstream signaling pathways.
Therefore, if a mutation occurs such that several of the tyrosines on the RTK cannot be phosphorylated, it is likely that the RTK will have a decreased ability to dimerize.
However, the specific effects of this mutation on RTK dimerization and subsequent downstream signaling pathways will depend on the location and number of tyrosine residues affected. If the mutation only affects a few tyrosine residues, the RTK may still be able to dimerize through other available tyrosine residues, albeit with reduced efficiency. If a larger number of tyrosine residues are affected, the RTK may not be able to dimerize at all.
In either case, the effects of this mutation on RTK function will likely be detrimental, as dimerization and downstream signaling are crucial for RTK-mediated cellular processes such as cell growth, differentiation, and survival. Therefore, it is important to consider the potential consequences of mutations that affect RTK phosphorylation and dimerization when studying their roles in various cellular processes and diseases.

Groups of living things called species can interbreed to create fertile offspring and have similar traits.
Biology is based on the idea of species, which is used to categorize and comprehend the diversity of life on Earth. Millions of species have been identified, ranging from simple single-celled organisms to sophisticated multicellular organisms like humans.
They regulate populations, provide food and nutrients for other creatures, and contribute to ecosystem services like pollination and nutrient cycling, among other vital ecological tasks.
Over millions of years, species have changed due to factors like natural selection, genetic drift, and gene flow. Threats to numerous species today include habitat loss, climate change, pollution, and overexploitation by humans.
